Render xdot formatted graphs

Description

Canviz is a wiki macro plugin to render xdot formatted graphs. Canviz is a JavaScript and ​Canvas based graph rendering library available on Google Code.

xdot is a more extensive format than ​dot for graphs. It is used merely because that is what the Canviz project uses.

I created this plugin to have something simpler than Graphviz and to push rendering out to the browser rather than on the server. You do not need to install Graphviz, unless you need access to the dot utility (see below).

An example Hello World for a Trac wiki is as follows:

{{{
#!canviz
digraph G {
	node [label="\N"];
	graph [bb="0,0,74,108",
		_draw_="c 5 -white C 5 -white P 4 0 0 0 108 74 108 74 0 ",
		xdotversion="1.2"];
	Hello [pos="37,90", width="0.92", height="0.50", _draw_="c 5 -black e 37 90 33 18 ", _ldraw_="F 14.000000 11 -Times-Roman c 5 -black T 37 85 0 32 5 -Hello "];
	World [pos="37,18", width="1.03", height="0.50", _draw_="c 5 -black e 37 18 37 18 ", _ldraw_="F 14.000000 11 -Times-Roman c 5 -black T 37 13 0 37 5 -World "];
	Hello -> World [pos="e,37,36 37,72 37,64 37,55 37,46", _draw_="c 5 -black B 4 37 72 37 64 37 55 37 46 ", _hdraw_="S 5 -solid S 15 -setlinewidth(1) c 5 -black C 5 -black P 3 41 46 37 36 34 46 "];
}
}}}

Canviz uses the XDOT format. To convert from DOT to XDOT you can use the dot command. To create the above example from DOT:

echo "digraph G {Hello->World}" | dot -Txdot -otemp.xdot

which produces the image:

Note: a graphing library offering similar features and with a lower barrier to entry is the MermaidMacro.
