status="ready" · three sets, seven disjoint regions. Circle area is proportional to set size, and every pair sits at the distance that solves lens area = the count the two sets share; the middle region is whatever the geometry leaves over, and the component measures it before accepting the drawing (worst region here is 0.50 points off, inside the three-point budget).

Channel reach overlap. Venn diagram of 3 sets over 13,240 accounts in at least one of them. Push 7,980 (60.3%), Email 7,220 (54.5%), SMS 3,300 (24.9%). Largest shared region — In Push and Email, not SMS — 2,340 (17.7%). Circle areas are proportional to the counts; the largest gap between a region's drawn share and its true share is 0.5 points. All 7 regions are listed in the table below.

Every region of the 3-set comparison, from the parts that belong to one set to the part they all share. Regions are disjoint, so the counts add up to the total.

Two sets · always exactly solvable, which is why these numbers come from faker on a fixed seed: the counts give the radii, and one bisection finds the centre distance that makes the lens exactly the shared count — worst drift 0.02 points.

Two sets always have an exact arrangement, whatever the counts
7,968 workspaces · 2 sets · 3 of 3 regions occupied
Trial vs invite. Venn diagram of 2 sets over 7,968 workspaces in at least one of them. Started a trial 6,259 (78.6%), Invited a teammate 3,384 (42.5%). Largest shared region — In Started a trial and Invited a teammate — 1,675 (21.0%). Circle areas are proportional to the counts; the largest gap between a region's drawn share and its true share is 0.0 points. All 3 regions are listed in the table below.

Three sets that cannot be drawn · every pair shares 450 people, yet nobody holds all three certificates. Any circles that honour those three pairwise overlaps leave a middle region (measured at 14.7% of the picture); the component measures that region — drawn, but holding nobody — refuses the drawing, and prints a labelled table instead of three circles parked in fixed positions.

Three identical sets · every pairwise distance solves to 0 and the three circles coincide into one ring. That is geometrically honest: the six partial regions really do have zero area, so none of them is labelled, and the one region with people in it takes the label at the centre.

Circle areas are proportional to the counts. Largest gap between a region's drawn share and its true share: 0.0 points (In Billing, not Invoicing or Payments).
One category takes 100% · the other two sets have no members, and a zero-area circle has neither a radius nor a place to sit, so it falls back to the table and names which sets are empty.

Labels give ground one step at a time · Email ∩ SMS is 3 accounts, and the largest circle that fits inside that lens has an 11.4px radius — room for the count but not the share, so only the count is drawn. Both numbers stay in the hover readout and in the table below.
