This class basically it's an opinionated ES6 class wrapper for a d3 force graph using svg.
You can call the add/remove methods to add and remove nodes and
links dynamically. It has drag, zoom, pan, etc., built in with
overridable methods for each.
Each node is a node group (instead of a simple "circle"), with each node shape being either a circle or a rect. You can have node images, node labels, node hyperlinks (because I used vimperator RIP, VimFX and others don't quite pick up the buried tags).
Just about every possible data function is exposed as an overridable
method, e.g. handleDragged(d), getNodeShape(d), etc. If something
is not exposed, then you can override the corresponding init function
to tweak it. NOTE: This comes possibly at a cost of performance, but
I haven't done any benchmarks. This class is more about convenience
than high performance.
There is also a slightly tested child graph functionality, which duplicates the parent graph, but I haven't used it yet in production.
