CLUSTER EDITOR-MARKDOWN-MERMAID · 8 ENTRIES · EARLIEST ENTRY 2026-02-07

Mermaid-enabled Markdown editors

The cluster comprises Markdown editors and plugins that render Mermaid diagrams for document preview and note-taking. The dated history before the index start includes only four entries, too few to discern a shape, so the cluster either predates the index or its members are largely undated. On traction, SketchMD leads with 3 stars, while the others have none.

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.
