Are there event listeners to detect mouse clicks on dot/SVG graph?

Question

I am playing with generating dot files and then turned them into SVG graphs with a lot of nodes.

My question is that are there event listeners to detect mouse clicks on dot/SVG graph nodes?

For example, right click on a node in the SVG graph, I do something(maybe get the related information from the node and then do something),

Then how to generate dot file or SVG file to achieve this?

Answer 1

There are several ways to create an interactive SVG graph:

• Use SMIL, an extension to svg (Example tutorial http://apike.ca/prog_svg_smil.html)
• Javascript (the Raphael library is excellent)
• CSS animations

In any case, you'll have to display the svg graphs in a client which supports any of those technologies (browser), and you will have to code it in addition to the svg output graphviz creates.
