Choose honest evidence and charts

The idea in everyday life
Select data, examples, quotations, and visuals that clarify the claim without distortion.
Evidence earns belief only when the audience can see what it shows, what it does not, and where it came from.
One step at a time.
Use the sample or information you have permission to use. Keep your work as you go. You can pause between steps.
- 1
Verify definitions, date ranges, sample, units, comparison baseline, and source for every material number.
- 2
Choose chart forms by relationship: comparison, trend, distribution, composition, correlation, or process.
- 3
Use honest axes, direct labels, necessary context, and emphasis that highlights rather than manipulates.
- 4
Cite sources on the slide or in accessible notes and obtain rights for third-party imagery.
See how it works.
Priya replaces a 3D pie chart with a labeled cohort trend and notes that the latest cohort has only 30 days of follow-up.
Did you cover these?

- Check this common mistake: Truncating axes, mixing definitions, or decorating weak evidence until the result looks more certain than it is.
- A skeptical viewer can trace each major claim to a readable source and interpret the visual correctly without narration.
