Data Driven Parallel Coordinates to Chord Diagram

This example is interesting in a couple of ways.

First, it demonstrates the ability of dex.js to construct charts from data. This construction can include interactions as well.

Secondly, the interaction itself is interesting. By selecting the axis on the parallel coordinates chart the chord diagram is updated showing the relationships of the selected data.

dex.create

The dex.create method takes a json specification and constructs the components it describes but does not render them.

dex.render

The dex.render method takes a json specification, constructs and renders it. An array of constructed components is returned.
