Notes
Hierarchical Edge Bundling helps you to visualize adjacency relations between leaf nodes organized in a hierarchy with parent nodes. It will bundle the adjacency leaf nodes together to reduces visual clutter.
Once you have created a Hierarchical Edge Bundling diagram, you can
- Control how to show the connect lines
- Show bubbles for leaves and control the display format
- Select a grouping column as Subset to group the leaves together and show nodes for the groups if needed
