Chord diagram · Known zero
Zero nodes remain markers. Zero-weight links have no invented area and remain available through navigation and source data.
Use it for symmetric connections and collaboration. Endpoint order does not imply direction; the tooltip reports incident totals rather than incoming and outgoing values.
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.
