Chord Diagrams
Chord diagrams, also known as radial network diagrams, are a form of data visualisation that have become quite popular partly because of how colourful and eye-catching they can be. In this video, we'll go from concept to code, starting with the anatomy of a chord diagram.

Instructional video
In the video below, I cover how to create a chord diagram from concept to code.
Background
I created a synthetic dataset to use an example throughout the video. I'm happy with how it turned out - it's very colourful!
Dataset. 26 artists were asked to share up to 2 of their favourite colours.
I then show how to populate a co-occurrence matrix from the dataset.
Once our data is wrangled into the required form, we move onto using Python to create a chord diagram with PlotAPI.
matrix = [
[0, 5, 0, 0, 4, 0],
[5, 0, 0, 0, 0, 5],
[0, 0, 2, 4, 0, 0],
[0, 0, 4, 3, 3, 0],
[4, 0, 0, 3, 0, 0],
[0, 5, 0, 0, 0, 0],
]
names=['purple','pink','orange','lime','green','blue']
Chord(matrix, names).show()
