Graphviz supports CSS stylesheets for SVG ouptut. There's an attribute stylesheet in the documentation.
Should the attribute stylesheet be given separately to all the nodes? How can I set a stylesheet for all the graph elements just writing the CSS filename to one place only? Where?
The attribute stylesheet is given to a graph definition. See the sample below.
sample.dot
graph sample {
stylesheet="sample.css"
a [class="sky"]
b [class="ground"]
a -- b
}
sample.css
.sky>ellipse {
fill: deepskyblue;
}
.ground>ellipse {
fill: palegreen;
}
command
dot -Tsvg < sample.dot > sample.svg
sample.svg
