What we audit

Chart Type Fit

Did you pick the right chart? Sometimes a slope chart, dot plot, or table tells the story better than what you have.

Color & Accessibility

Color blind safety, contrast ratios, and whether color carries meaning or just decoration.

Data-Ink Ratio

Tufte's principle — every pixel should carry information. We flag 3D effects, heavy gridlines, redundant legends.

Narrative Clarity

Does the title state the insight, or just label the data? A great chart has a single, unmistakable takeaway.

Executive Readability

Can a senior leader grasp the point in 5 seconds? We score font sizes, label density, and key-number prominence.

Annotation Quality

Are critical points called out? Is context (benchmarks, targets, units, sources) explicit?
