Is there an easy way to be able to click in complex graphs (exported as SVG, and embedded in an HTML page) so that the edge clicked is highlighted, as well as the nodes attached to it?

[when you say highlight, I assume you will accept changing line or fill color]
I know of no “built-in” way to do what you ask, however:
- CSS seems to support changing colors based on “hover” (not click) (you would use the Graphviz “class” attribute)
