dont-slice-one-circle-between-unrelated-measures

Put several measures that share no whole onto concentric arcs instead of slicing one circle between them, cap the largest sweep short of 360°, and draw value wedges over a full-ring track. Use when a donut/pie is about to encode counts that do not add up to anything, when the biggest ring looks identical to a full one, or when an "almost nothing here" bucket reads as a missing tick.
