I'm creating a diagram with D3 and JSON which is based on this:
http://bl.ocks.org/mbostock/4063550
The difference is, I also want to have different shapes for nodes (not just circles, but for example, trianges.)
I have a attribute in the JSON file that says something like "shape":"triangle".
How do I update that index.html file so that I can get different shapes to be displayed?
Really urgently need assistance...any help/advice really appreciated.
