# Make AI account for overlapping segments in a chart

Specify whether categories overlap and inspect denominator and double counting.

Use the supplied source as authority. Check the account supports the actual file or image operation before attempting it.

## Task instruction

Chart these supplied segment counts for [population and period].
Categories [can/cannot] overlap according to [source definition].
Use the supplied population as denominator where appropriate.
Do not add overlapping counts and call the sum unique people or a whole.
If a partition is needed, use verified exclusive components and show
their derivation. Keep unknown overlap unresolved, with a source table
and a text explanation. Do not invent membership to complete the chart.

## Source boundaries

- Population 30
- Marketing 20; Finance 15
- Both 8

## Review and correction

20 + 15 counts eight people twice. The union is 27, with 3 in neither. Schematic circle area is not quantitative.

The draft treats [overlapping categories] as exclusive and uses [wrong
denominator]. The source supplies [population and overlap]. Correct
the counts, denominator and visual relationship together. Keep source
values unchanged and explain the derivation. Do not invent a missing
overlap or force unrelated percentages to sum to 100.
