status="ready" · 24 hours at 15° each, radius corrected for area. The 08:00 peak of 940 against the 03:00 low of 45 is a 20.9× spread; 02:00 is null (the counter was offline), not 0; the dashed ring is the 443.4 mean of the 23 hours that reported.

Polar area chart of Bike hires · by hour of day: 24 equal 15 degree periods around one turn of the day, radius area-corrected. Peak 08:00 at 940 hires, 20.9 times the low at 03:00, 45 hires. 9 of 23 reported periods sit above the mean of 443.39 hires. Total 10,198 hires. 1 period has no reading and is outlined rather than filled. Every period is listed in the table that follows.

Every period owns the same 15° of the turn; the radius is area-corrected, so it is the ink of a sector — not how far it reaches — that is proportional to its value. Dashed ring: the mean, 443.39 hires.
1 period has no reading at all — outlined, never filled.

radiusScale="linear" holeRatio={0} · the same data with the radius set straight to the value and no hub: area grows with the square of the radius, so a 20.9× gap between 940 and 45 is painted as 436× the ink (about 95× with the default hole). The chart above is the default for a reason.

Degenerate input · one month takes 100% of the year (Dec 5,400) and the other eleven measured exactly 0. A 0 is a reading, not a gap, so it is drawn as a tick on the floor ring rather than eleven holes that look like missing data.

Degenerate input · two months of negative net growth (Feb −320, Aug −80), one failed export (null), two months that measured 0, and a label nobody trimmed. A negative number has no arc, so it is hatched at the hub and named in the footnote — never clamped to 0 and slipped in as an ordinary short petal.
