Generate graph in PNG using metapost
First you need to install metapost
and imagemagick
.
Then this code provide a nice code to draw graphs and automata.
Furthermore the script gen
generate only PNG optimized for the web.
Example
z0=origin;
z1=(gu,0);
z2=(2gu,0);
z3=(3gu,0);
drawState(z0,"A");
drawState(z1,"B");
drawState(z2,"C");
drawState(z3,"D");
drawEdge(z1,z2,"g");
drawoptions(withcolor blue);
drawEdgeAngle(z0,z2,"g\circ f",35);
drawEdge(z2,z3,"h");
drawoptions(withcolor green);
drawEdge(z0,z1,"f");
drawEdgeAngle(z1,z3,"h\circ g",-35);
drawoptions(withcolor yellow);
drawEdgeAngle(z0,z3,"(h\circ g)\circ f = h\circ (g\circ f)",50);
