When to use this template
A Chord Diagram excels at illustrating the strength and direction of relationships or flows between a fixed set of entities. It helps analysts quickly identify dominant connections, understand the distribution of interactions across all pairs, and spot highly connected or isolated groups within a system. This visualization is chosen to reveal patterns of exchange, collaboration, or movement across distinct categories.
- Data representing a square, symmetric or asymmetric matrix of relationships.
- A moderate number of distinct categories (typically 5-20) for optimal readability.
- Quantitative values indicating the strength, volume, or frequency of connection.
- Bidirectional or directional flow data where source and target entities are from the same set.
- Datasets where self-loops (connections within the same category) are zero or not relevant.
- Categorical data with an associated quantitative measure of interaction between pairs.
