I've been using Vis.js and http://shaky.github.bushong.net/. You can do really cool stuff with them. Highly recommend them both. I will import those into gimp and create all types of animation with them [1, 2]. I've built a db backend for vis.js and it makes to super simple to connect things and saves the positions for Vis.js. You can see a demo of it here: https://sysadmincasts.com/map. Try zooming in/out, moving things, etc. I should probably open-source the code as others might like an example of it too.
