Cumulative wiki pages per spoke, by each page's created: date —
405 pages across 14 spokes, 5/29–6/17.
The top (black) edge is the hub total. Bands are stacked oldest-spoke-first.
Caveat: the x-axis is each page's authored date (created:),
so pages migrated between spokes (splits/merges) keep their original date — this shows when
content was written, not when it landed in its current spoke. Hover a band for its name
and current size.
