Arc diagram · Visibility groups

Hide and restore a source group; visible incident totals and weights are recomputed.

Use it when source node order matters. Arc thickness represents relation weight. Node radius is a layout choice, not a second measure.

Stable nodes and link IDs, explicit endpoints and non-negative measured values. null is unknown; zero is known. Visibility groups are optional. Unknown links stay in the source table; node totals disclose incomplete data.

Up to 64 nodes, 256 links and 15 explicit groups plus the default group. Node and link IDs are globally unique. Self-links, axes, stacking, references and viewport transforms are not supported in this version.
