# What is the name of this visualization with a circle and internal arcs?

I came across this visualization where there is a circle with data points on the circle and internal lines (arcs or edges) between the points on the circle. What is the name of this type of visualization?

How would I generate it from a 2-D table like the one below? I want the points A, B, C, D, and E on the circle and the value from point i to j to be an arc between them. Would something like d3.js be able to generate it?

This is a chord diagram. It is usuallly generated from a square matrix like the one you have. This can be done with specific libraries at least in R (circlize package) and Python (plotly). It's also possible to do it with d3.js but apparently not so easily.

General advice: I find the "X Graph Gallery" websites quite convenient for exploring different types of graphs: R graph gallery, Python graph gallery and D3 graph gallery.

• Thank you. Those graph galleries are very helpful. Jan 9 at 1:40
