This is a simple demonstration of using NetworkX and d3.js (v4.0) to produce an interactive network graph from a sample dataset. In this case I've used the Marvel Comics Network data from R. Alberich, J.Miro-Julia, and F. Rossello.

The resulting network graph extends Mike Bostock's simple graph demo with some additional features that could be useful for DH scholars interested in networks. I've included a slider that redraws the network based on edge weights, a dropdown for three different types of node centrality, and the ability to click on nodes to see ego networks.

You can see a working demo of the network at this bl.ocks.org page.
