Bad Chart Autopsy

FORENSIC VISUALIZATION UNIT · CASE 24-08

A chart can render perfectly and still fail its reader.

This benchmark chart arrived with a confident headline and valid data. We will preserve the evidence, identify the visual tricks, choose a better chart, and ask Semiotic to prove the replacement before it leaves the lab.

Submitted claim“Atlas crushes the competition.”

PROCEDURE 01

Intake

Evidence A-01SUSPECT

THE TRUST LOOP

Validate the shape. Audit the data. Diagnose the design. Prove the scene. Name what remains manual.
