Chord Diagram
Chord diagrams visualize relationships or flows between a set of entities arranged radially around a circle. Connections between entities are shown as arcs (chords) inside the circle. The thickness of the chord often represents the magnitude of the flow or relationship between the two connected entities.

Chord diagrams visualize relationships or flows between a set of entities arranged radially around a circle. Connections between entities are shown as arcs (chords) inside the circle. The thickness of the chord often represents the magnitude of the flow or relationship between the two connected entities.
Examples
Migration flows between regions A, B, and C
Chart Visualization
This example includes an interactive chart visualization with 4 data points.
Chart type: chord
Usage
Best Used For
- Visualizing relationship matrices or flow data between distinct groups
- Showing bidirectional flows or co-occurrence patterns
- Comparing the strength of connections between entities
- Displaying network connectivity in a compact, circular format
Data Requirements
[Object]
Limitations
Important Considerations
- ⚠Can become cluttered with many entities or dense connections
- ⚠Difficult to interpret exact values from chord thickness alone
- ⚠Less intuitive for audiences unfamiliar with the format
- ⚠Labeling entities around the circle can be challenging with many segments
