Chord Chart

[kristof-taveirne]

Describe your motivation

A chord chart is a beautiful representation of bi-directional relationships between concepts.

The edge of the chart is a donut, the links between the parts of the donut represent the relationships and the strength between them.

We are currently in the process of migrating away from D3 towards Vaadin Charts, and this is the only one we are missing to complete our migration. For the time being we are using a Heatmap to read the visualize the same information. The bi-directional relationship is a bit clearer when using a Chord chart.

Describe the solution you'd like

A feature equivalent implementation of the D3 Chord Chart as a valuable addition to the Vaadin Charts.

Describe alternatives you've considered

Writing our own wrapper around the D3 Chord Chart component.
We've gone for Heatmap instead as it kind of shows the same information with a bit of extra mental effort

@yuriy-fix Is vaadin-charts still a wrapper around Highcharts? Or was that only in the Vaadin 6,7,8 days?

[yuriy-fix]

Yes, Vaadin Charts is still a wrapper around Highcharts in recent versions
