NAME

       patchwork - filter for drawing clustered graphs as treemaps

SYNOPSIS

       patchwork [-(G|N|E)name=value] [-Tlang] [-llibfile] [-ooutfile] [-O] [-P] [-v] [-V] [files]

DESCRIPTION

       patchwork  draws clustered graphs using a squarified treemap layout.  As input, it takes any graph in the
       dot format. Each cluster is given an area based on the areas specified  by  the  clusters  and  nodes  it
       contains.  The  areas  of  nodes  and empty clusters can be specified by the area attribute.  The default
       value is 1.

       The root graph is laid out as a  square.  Then,  recursively,  the  region  of  a  cluster  or  graph  is
       partitioned  among  its top-level nodes and clusters, with each given a roughly square subregion with its
       specified area.

OUTPUT FORMATS

       Patchwork uses an extensible plugin mechanism for its output renderers, so to  see  what  output  formats
       your installation of patchwork supports you can use ``patchwork -Txxx'' (where xxx is an unlikely format)
       and  check  the  warning  message.   Also,  The plugin mechanism supports multiple implementations of the
       output formats.  To see what variants are available, use, for example: ``patchwork -Tpng:'' and to  force
       a particular variant, use, for example: ``patchwork -Tpng:gd''

       Traditionally,  patchwork  supports  the  following:  -Tps  (PostScript), -Tsvg -Tsvgz (Structured Vector
       Graphics), -Tfig (XFIG graphics), -Tmif (FrameMaker  graphics),  -Thpgl  (HP  pen  plotters),  and  -Tpcl
       (Laserjet  printers),  -Tpng -Tgif (bitmap graphics), -Tdia (GTK+ based diagrams), -Timap (imagemap files
       for httpd servers for each node or edge that has a  non‐null  "href"  attribute.),  -Tcmapx  (client‐side
       imagemap  for  use in html and xhtml).  Additional less common or more special‐purpose output formats can
       be found at http://www.graphviz.org/doc/info/output.html.)

       Alternative plugins providing support for a given output format can  be  found  from  the  error  message
       resulting from appending a ':' to the format. e.g. -Tpng: The first plugin listed is always the default.

GRAPH FILE LANGUAGE

       Here is a synopsis of the graph file language, normally using the extension .gv, for graphs:

       [strict] (graph|digraph) name { statement‐list }
       Is the top level graph. If the graph is strict then multiple edges are not allowed between the same pairs
       of  nodes.   If  it  is a directed graph, indicated by digraph, then the edgeop must be "->". If it is an
       undirected graph then the edgeop must be "--".  Statements may be:

       name=val;
       node [name=val];
       edge [name=val];
       Set default graph, node, or edge attribute name to val.  Any subgraph, node, or edge appearing after this
       inherits the new default attributes.

       n0 [name0=val0,name1=val1,...]; Creates node n0 (if it does not already exist) and  sets  its  attributes
       according to the optional list.

       n0 edgeop n1 edgeop ... edgeop nn [name0=val0,name1=val1,...];
       Creates  edges  between  nodes  n0, n1, ..., nn and sets their attributes according to the optional list.
       Creates nodes as necessary.

       [subgraph name] { statement‐list }
       Creates a subgraph.  Subgraphs may be used in place of n0, ..., nn in  the  above  statements  to  create
       edges.  [subgraph name] is optional; if missing, the subgraph is assigned an internal name.

       Comments may be /*C‐like*/ or //C++‐like.

       Attribute  names  and  values are ordinary (C‐style) strings.  The following sections describe attributes
       that control graph layout.

GRAPH ATTRIBUTES

       size="x,y" sets bounding box of drawing in inches.

       page="x,y" sets the PostScript pagination unit.

       ratio=f sets the aspect ratio to f which may be a floating point number, or one  of  the  keywords  fill,
       compress, or auto.

       pagedir=[TBLR][TBLR] sets the major and minor order of pagination.

       rotate=90 sets landscape mode.  (orientation=land is backward compatible but obsolete.)

       center=n a non‐zero value centers the drawing on the page.

       layers="id:id:id:id"  is  a  sequence  of  layer  identifiers for overlay diagrams.  The PostScript array
       variable layercolorseq sets the assignment of colors to layers. The least index is  1  and  each  element
       must be a 3‐element array to be interpreted as a color coordinate.

       color=colorvalue sets foreground color (bgcolor for background).

       href="url"  the default url for image map files; in PostScript files, the base URL for all relative URLs,
       as recognized by Acrobat Distiller 3.0 and up.

       URL="url" ("URL" is a synonym for "href".)

       stylesheet="file.css" includes a reference to a stylesheet in -Tsvg and -Tsvgz outputs.  Ignored by other
       formats.

       splines. If set to true, edges are drawn as splines.  If set to polyline, edges are drawn  as  polylines.
       If  set  to  ortho,  edges  are  drawn as orthogonal polylines.  In all of these cases, the nodes may not
       overlap.  If splines=false or splines=line, edges are drawn as line segments.  The default is false.

NODE ATTRIBUTES

       height=d or width=d sets minimum height or width.  Adding fixedsize=true forces these to  be  the  actual
       size (text labels are ignored).

       shape=record polygon epsf builtin_polygon
       builtin_polygon is one of: plaintext ellipse oval circle egg triangle box diamond trapezium parallelogram
       house  hexagon octagon note tab box3d component.  (Polygons are defined or modified by the following node
       attributes: regular, peripheries, sides,  orientation,  distortion  and  skew.)   epsf  uses  the  node's
       shapefile  attribute  as  the  path name of an external EPSF file to be automatically loaded for the node
       shape.

       label=text where text may include escaped newlines \n, \l, or \r for center, left,  and  right  justified
       lines.   The string '\N' value will be replaced by the node name.  The string '\G' value will be replaced
       by the graph name.  Record labels may contain recursive box lists delimited by { | }.   Port  identifiers
       in labels are set off by angle brackets < >.  In the graph file, use colon (such as, node0:port28).

       fontsize=n sets the label type size to n points.

       fontname=name sets the label font family name.

       color=colorvalue  sets the outline color, and the default fill color if style=filled and fillcolor is not
       specified.

       fillcolor=colorvalue sets the fill color  when  style=filled.   If  not  specified,  the  fillcolor  when
       style=filled defaults to be the same as the outline color.

       fontcolor=colorvalue sets the label text color.

       A  colorvalue  may be "h,s,v" (hue, saturation, brightness) floating point numbers between 0 and 1, or an
       X11 color name such as white black red green blue yellow magenta cyan or burlywood, or a "#rrggbb"  (red,
       green, blue, 2 hex characters each) value.

       style=filled solid dashed dotted bold invis or any Postscript code.

       layer=id or id:id or "all" sets the node's active layers.  The empty string means no layers (invisible).

       The following attributes apply only to polygon shape nodes:

       regular=n  if  n  is  non‐zero  then  the polygon is made regular, i.e. symmetric about the x and y axis,
       otherwise the polygon takes on the aspect ratio of the label.   builtin_polygons  that  are  not  already
       regular  are  made regular by this attribute.  builtin_polygons that are already regular are not affected
       (i.e.  they cannot be made asymmetric).

       peripheries=n sets the number of periphery lines drawn around the polygon.   This  value  supersedes  the
       number of periphery lines of builtin_polygons.

       sides=n sets the number of sides to the polygon. n<3 results in an ellipse.  This attribute is ignored by
       builtin_polygons.

       orientation=f  sets  the orientation of the first apex of the polygon counterclockwise from the vertical,
       in degrees.  f may be a floating point number.  The  orientation  of  labels  is  not  affected  by  this
       attribute.  This attribute is added to the initial orientation of builtin_polygons.

       distortion=f  sets  the  amount  of  broadening  of  the  top  and narrowing of the bottom of the polygon
       (relative to its orientation).  Floating point values between -1 and +1 are suggested.  This attribute is
       ignored by builtin_polygons.

       skew=f sets the amount of right‐displacement of the top  and  left‐displacement  of  the  bottom  of  the
       polygon  (relative  to  its  orientation).   Floating point values between -1 and +1 are suggested.  This
       attribute is ignored by builtin_polygons.

       href="url" sets the url for the node in imagemap, PostScript and SVG files.  The substrings '\N' and '\G'
       are substituted in the same manner as for the node label attribute.  Additionally the substring  '\L'  is
       substituted with the node label string.

       URL="url" ("URL" is a synonym for "href".)

       target="target"  is  a  target string for client‐side imagemaps and SVG, effective when nodes have a URL.
       The target string is used to determine which window of the browser is used for the URL.   Setting  it  to
       "_graphviz"  will  open  a new window if it doesn't already exist, or reuse it if it does.  If the target
       string is empty, the default, then no target attribute is included in the output.   The  substrings  '\N'
       and  '\G' are substituted in the same manner as for the node label attribute.  Additionally the substring
       '\L' is substituted with the node label string.

       tooltip="tooltip" is a tooltip string for client‐side imagemaps and SVG, effective when nodes have a URL.
       The tooltip string defaults to be the same as the label string, but this attribute permits nodes  without
       labels  to  still  have  tooltips  thus  permitting  denser  graphs.   The  substrings  '\N' and '\G' are
       substituted in the same manner as for the node label  attribute.   Additionally  the  substring  '\L'  is
       substituted with the node label string.

EDGE ATTRIBUTES

       label=text  where  text may include escaped newlines \n, \l, or \r for centered, left, or right justified
       lines.  If the substring '\T' is found in a label it will be replaced by  the  tail_node  name.   If  the
       substring  '\H'  is  found  in  a label it will be replaced by the head_node name.  If the substring '\E'
       value is found in a label it will be replaced by: tail_node_name->head_node_name If the substring '\G' is
       found in a label it will be replaced by  the  graph  name.   or  by:  tail_node_name--head_node_name  for
       undirected graphs.

       fontsize=n sets the label type size to n points.

       fontname=name sets the label font family name.

       fontcolor=colorvalue sets the label text color.

       style=solid dashed dotted bold invis

       color=colorvalue sets the line color for edges.

       color=colorvaluelist a ':' separated list of colorvalue creates parallel edges, one edge for each color.

       dir=forward back both none controls arrow direction.

       tailclip,headclip=false disables endpoint shape clipping.

       href="url"  sets  the url for the node in imagemap, PostScript and SVG files.  The substrings '\T', '\H',
       '\E' and '\G' are substituted in the same manner as for  the  edge  label  attribute.   Additionally  the
       substring '\L' is substituted with the edge label string.

       URL="url" ("URL" is a synonym for "href".)

       target="target"  is  a  target string for client‐side imagemaps and SVG, effective when edges have a URL.
       If the target string is empty, the default, then no target attribute is  included  in  the  output.   The
       substrings  '\T', '\H', '\E' and '\G' are substituted in the same manner as for the edge label attribute.
       Additionally the substring '\L' is substituted with the edge label string.

       tooltip="tooltip" is a tooltip string for client‐side imagemaps effective when edges  have  a  URL.   The
       tooltip  string  defaults  to  be the same as the edge label string.  The substrings '\T', '\H', '\E' and
       '\G' are substituted in the same manner as for the edge label attribute.  Additionally the substring '\L'
       is substituted with the edge label string.

       arrowhead,arrowtail=none, normal, inv, dot, odot, invdot, invodot, tee, empty, invempty, open,  halfopen,
       diamond, odiamond, box, obox, crow.

       arrowsize (norm_length=10,norm_width=5, inv_length=6,inv_width=7,dot_radius=2)

       headlabel,taillabel=string for port labels.  labelfontcolor,labelfontname,labelfontsize for head and tail
       labels.   The  substrings  '\T',  '\H',  '\E' and '\G' are substituted in the same manner as for the edge
       label attribute.  Additionally the substring '\L' is substituted with the edge label string.

       headhref="url" sets the url for the head port in imagemap, PostScript  and  SVG  files.   The  substrings
       '\T',  '\H',  '\E'  and  '\G'  are  substituted  in  the  same  manner  as  for the edge label attribute.
       Additionally the substring '\L' is substituted with the edge label string.

       headURL="url" ("headURL" is a synonym for "headhref".)

       headtarget="headtarget" is a target string for client‐side imagemaps and SVG, effective when  edge  heads
       have  a URL.  The headtarget string is used to determine which window of the browser is used for the URL.
       If the headtarget string is empty, the default, then headtarget defaults to the same value as target  for
       the  edge.   The  substrings '\T', '\H', '\E' and '\G' are substituted in the same manner as for the edge
       label attribute.  Additionally the substring '\L' is substituted with the edge label string.

       headtooltip="tooltip" is a tooltip string for client‐side imagemaps effective when head ports have a URL.
       The tooltip string defaults to be the same as the headlabel string.  The substrings '\T', '\H', and  '\E'
       are  substituted  in the same manner as for the edge label attribute.  Additionally the substring '\L' is
       substituted with the edge label string.

       tailhref="url" sets the url for the tail port in imagemap, PostScript  and  SVG  files.   The  substrings
       '\T',  '\H',  '\E'  and  '\G'  are  substituted  in  the  same  manner  as  for the edge label attribute.
       Additionally the substring '\L' is substituted with the edge label string.

       tailURL="url" ("tailURL" is a synonym for "tailhref".)

       tailtarget="tailtarget" is a target string for client‐side imagemaps and SVG, effective when  edge  tails
       have  a URL.  The tailtarget string is used to determine which window of the browser is used for the URL.
       If the tailtarget string is empty, the default, then tailtarget defaults to the same value as target  for
       the  edge.   The  substrings '\T', '\H', '\E' and '\G' are substituted in the same manner as for the edge
       label attribute.  Additionally the substring '\L' is substituted with the edge label string.

       tailtooltip="tooltip" is a tooltip string for client‐side imagemaps effective when tail ports have a URL.
       The tooltip string defaults to be the same as the taillabel string.  The substrings '\T', '\H', '\E'  and
       '\G' are substituted in the same manner as for the edge label attribute.  Additionally the substring '\L'
       is substituted with the edge label string.

       labeldistance and port_label_distance set distance; also labelangle (in degrees CCW)

       decorate draws line from edge to label.

       samehead,sametail aim edges having the same value to the same port, using the average landing point.

       layer=id or id:id or "all" sets the edge's active layers.  The empty string means no layers (invisible).

       (neato‐specific attributes)
       w=f  sets the weight (spring constant) of an edge to the given floating point value.  The default is 1.0;
       greater values make the edge tend more toward its optimal length.

       len=f sets the optimal length of an edge.  The default is 1.0.

COMMAND LINE OPTIONS

       -G sets a default graph attribute.
       -N sets a default node attribute.
       -E sets a default edge attribute.  Example: -Gsize="7,8" -Nshape=box -Efontsize=8

       -lfile loads custom PostScript library files.  Usually these define custom shapes or styles.   If  -l  is
       given by itself, the standard library is omitted.

       -Tlang sets the output language as described above.

       -O automatically generate output filenames based on the input filename and the -T format.

       -v (verbose) prints various information useful for debugging.

       -V (version) prints version information and exits.

       -? prints the usage and exits.

EXAMPLES

       graph G {
         node[style=filled]
         subgraph cluster0 {
           subgraph cluster0_0 {
             style=filled
             fillcolor=green
             a b[area=3 fillcolor=yellow]
           }
           subgraph cluster0_1 {
              area=2
              bgcolor=yellow
           }
           c [style=filled
             fillcolor=red ]
         }
         subgraph cluster1 {
           e f
         }
       }

BUGS

       At  present, patchwork ignores edges, and supplies no visual clues to indicate nesting.  Such clues might
       consist of nested boxes or thicker rectangular outlines. In addition, it would be good  if  some  cluster
       label could be displayed.

       Patchwork has no mechanism for fitting labels within the supplied box.
