This Chord diagram shows the second step of the example used in my blog on Data-based orientations for gradients in a d3.js Chord Diagram
What you see here are movie collaborations between the Avengers in the MCU (up until & including Thor Ragnarok). Because collaborations are symmetrical, the chords are all as thick at the beginnen as at the end. Therefore, I wanted each chord to represent both the Avengers that it connects through a gradient. This is what you see in this step. In the next step we'll look at how to improve the chord ordering to prevent as much overlap as possible.
