FAQ
Chord Diagram Maker questions
- How is a chord diagram different from a Sankey?
- A Sankey flows left to right and cannot contain cycles. A chord diagram is circular and handles two-way relationships, so A to B and B to A both appear.
- What does the arc size around the edge mean?
- Each arc is sized by that entity total across all its connections, so the busiest entities occupy the most of the circle.
- How many entities can I show?
- Up to roughly a dozen. Past that the ribbons overlap heavily and a heatmap of the same matrix is easier to read.
