Diagram generation and layout libraries

This cluster comprises libraries and tools for programmatically generating and automatically laying out diagrams from various inputs, such as hardware descriptions, geometric data, clustering results, and graph structures. Dated entries are sparse and irregular, with six entries between 2019 and 2025, showing no clear trend or momentum. All traction leaders (tsqx, ogdf-docs, ogdf) have zero stars, indicating no significant activity signal among the members.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 8 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
