Check Your Understanding

1. What are the principles of honest graph design?

Answer: Start y-axis at zero (or clearly label if not), use consistent scales, show all relevant data, label everything clearly, use appropriate graph types, and avoid unnecessary 3D effects.

2. How do you redesign a misleading graph?

Answer: Identify the trick, then fix it: extend the axis to zero, use consistent bar widths, remove 3D effects, include all data points, and add proper labels and context.

3. Does an honest graph always look less dramatic?

Answer: Often yes — because honest graphs show reality, which is usually less extreme than misleading versions suggest. That is actually a good thing.

4. Why is it important to know how to make honest graphs?

Answer: Because if you can make misleading ones on purpose, you can spot them in the wild. And as a data scientist, your integrity depends on honest visualization.
