D3.js (http://d3js.org) is a popular interactive visualization framework for the Web. Written in JavaScript, it allows us to create data-driven visualizations based on Web technologies such as HTML, SVG, and CSS. There are many other JavaScript visualization and charting libraries, but we will focus on D3.js in this recipe.
Being a pure JavaScript library, D3.js has in principle nothing to do with Python. However, the HTML-based IPython notebook can integrate D3.js visualizations seamlessly.
In this recipe, we will create a graph in Python with NetworkX and visualize it in the IPython notebook with D3.js.
