What I'm wondering is whether there is an easy way for me to take an sbgn-ml file, render it in d3, and then add annotations on top of what is rendered to make it interactive.
See this blog post to get a sense of the interactivity I'm looking for: http://www.d3noob.org/2013/01/adding-tooltips-to-d3js-graph.html
