The year is a circle — orders by month
area ∝ orders (radius = √) · illustrative
Jan
Apr
Jul
Oct
Nov
Dec
Nov + Dec = 34% of the year
…and Dec touches Jan's trough —
the stock ordered for the peak
lands in the quietest month.
Radial charts flatter — radius is √orders here so area stays honest. Used only because the year genuinely wraps (the linear twin is the calendar, 30).
