I'm going to build a simple math graph for a browser application. Therefore all the JS-Vector Libraries might work out well. But I want to know about any experiences you collected using those. For me a basic feature is binding events to paths and points as well as animating paths.
Additionally I am thinking how they are mastering the future. I can imagine to export my drawings as an image or import SVG graphics. Did anyone already experience such cases? What about running them on mobile hardware like iPhone?
