Graphviz (dot) examples Some examples on how to use Graphviz.

Dotted edges etc

digraph D { A [shape=diamond] B [shape=box] C [shape=circle] A -> B [style=dashed, color=grey] A -> C [color="black:invis:black"] A -> D [penwidth=5, arrowhead=none] } Github respository about-Graphviz, path: /examples/dotted-edge.dot

Shape: record vs. plaintext If the shape attribute is set to record, the text (as controlled with the label attribute) is layouted in tabular form.

The vertical bar (|) starts a new row or column.

The curly braces { ... } change (flip) the direction of |.

digraph D { node [fontname="Arial"]; node_A [shape=record label="shape=record|{above|middle|below}|right"]; node_B [shape=plaintext label="shape=plaintext|{curly|braces and|bars without}|effect"]; } Github respository about-Graphviz, path: /examples/shape-record-vs-plaintext.dot

Multiple edges Normally, a dependency (an edge) is declared with an arrow: Node1 -> Node2. Multiple nodes can be listed in curly braces, thus declaring multple edges in one go. https://renenyffenegger.ch/notes/tools/Graphviz/examples/index

Left, mid and right aligned text \l

makes the preceeding text right aligned, \n makes it centered and \r makes it left aligned.

digraph L { node [shape=record fontname=Arial]; a b c

[label="one\ltwo three\lfour five six seven\l"] [label="one\ntwo three\nfour five six seven"] [label="one\rtwo three\rfour five six seven\r"]

Giving the graph a title With the label attribute, the graph can be given a caption: https://renenyffenegger.ch/notes/tools/Graphviz/examples/index

Graphviz (dot) examples

digraph D { label = "The foo, the bar and the baz"; labelloc = "t"; // place the label at the top (b seems to be default) node [shape=plaintext] FOO -> {BAR, BAZ}; } Github respository about-Graphviz, path: /examples/label.dot

HTML like labels If the text of label is enclosed in <…> rather than in "…", the text is treated as HTML and rendered as HTML like label.

digraph D { label = <The <font color='red'><b>foo</b></font>,<br/> the <font point-size='20'>bar</font> and< labelloc = "t"; // place the label at the top (b seems to be default) node [shape=plaintext] FOO -> {BAR, BAZ}; } Github respository about-Graphviz, path: /examples/label-html-like.dot

rank specifies that the specified nodes have the same rank, that is, that their distance from the top or left border is equal. { rank=same node_1 node_2 … }

Nested clusters

digraph D { subgraph cluster_p { label = "Parent"; subgraph cluster_c1 { label = "Child one"; a; subgraph cluster_gc_1 { label = "Grand-Child one"; b; } subgraph cluster_gc_2 { label = "Grand-Child two"; c; d; } } subgraph cluster_c2 { https://renenyffenegger.ch/notes/tools/Graphviz/examples/index

HTML table HTML tables are produced if the value of the label attribute is enclosed in <â&#x20AC;Ś> rather than "â&#x20AC;Ś":

digraph H { aHtmlTable [ shape=plaintext color=blue // The color of the border of the table label=< <table border='1' cellborder='0'> <tr><td>col 1</td><td>foo</td></tr> <tr><td>COL 2</td><td>bar</td></tr> </table> >]; } Github respository about-Graphviz, path: /examples/html-table.dot

Nested HTML table HTML tables can be nested

digraph { tbl [ shape=plaintext label=< <table border='0' cellborder='1' color='blue' cellspacing='0'> <tr><td>foo</td><td>bar</td><td>baz</td></tr> <tr><td cellpadding='4'> <table color='orange' cellspacing='0'> <tr><td>one </td><td>two </td><td>three</td></tr> <tr><td>four </td><td>five </td><td>six </td></tr> <tr><td>seven</td><td>eight</td><td>nine </td></tr> </table> </td> <td colspan='2' rowspan='2'> <table color='pink' border='0' cellborder='1' cellpadding='10' cellspacing='0'> https://renenyffenegger.ch/notes/tools/Graphviz/examples/index

Colors A color is specified with one of the attributes that relate to colors.

digraph D { node [shape=plaintext] some_node [ label=< <table border="0" cellborder="1" cellspacing="0"> <tr><td bgcolor="yellow">Foo</td></tr> <tr><td bgcolor="lightblue"><font color="#0000ff">Bar</font></td></tr> <tr><td bgcolor="#f0e3ff"><font color="#ff1020">Baz</font></td></tr> </table>> ];
