How to choose the right chart type to avoid misleading the audience?

All answers to this question.

Avoid 3D charts and decorative "chart-junk" at all costs. They distort the viewer's perception of area and volume. In 2024, the standard is "Functional Aesthetics." For time-series data, always use a line chart with a zero-baseline where possible. If you must truncate an axis to show small variations, you must clearly label the break. We once caught an error in a 2023 quality audit where a dual-axis chart made two unrelated metrics look correlated. Since then, we've enforced a "Simple over Sexy" rule for all executive dashboards to ensure total transparency.

Is there ever a legitimate use case for a Pie Chart, or should they always be replaced with Bar Charts for better comparison of values?

• William, pie charts are only okay for showing "part-to-whole" relationships with 2 or 3 categories. Anything more than that, and the human eye can't accurately compare the slice sizes.

Scatter plots are the best for showing correlations, but they require a "literate" audience. Always provide a brief explanation on how to read them during the talk.

• Exactly, Jessica. Part of storytelling is "Audience Education." You can't tell a story if the audience is struggling to decode the visual language you're using.
