d3-force

D3 Version 4 has more utilities and examples of interactions with Canvas. Here's an example of a relatively small graph (~500 nodes, 10k edges) that SVG used to struggle with, but Canvas renders with ease. http://bl.ocks.org/syntagmatic/954b31aa8b8beb91b30ccb0c9e57f... Notice the nodes are draggable, an interaction supported by the new simulation.find https://github.com/d3/d3-force/#simulation_find

Hmm. It might be possible, though it doesn’t sound like a great idea to have both D3 3.x and the D3 4.0 default bundle loaded simultaneously, since there will be a lot of overlap. A better strategy might be to load just the new modules you want to use. Like if you just want the new force layout, then load d3-force: https://github.com/d3/d3-force But it might be best to just migrate to 4.0. I know the changelist is long, but it might not be as hard as you think to migrate. And you can always send your questions to the d3-js Google group or d3.js on Stack Overflow and I’ll try to help.
