Grammar diagram generators

Cluster of tools that transform grammar specifications like EBNF into railroad diagrams for documentation, with one variant converting natural-language descriptions into set-builder notation. The available dated history is too thin to discern a trend, as only four dated entries exist before the index start. Traction leaders are useless-set-converter, ebnf-rr, and python-syntrax, all showing zero stars, indicating early-stage development.

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 4 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
