Radar chart
A radial multivariate chart that plots several measures on axes sharing a center, producing a profile shape.
Use this diagram to generateUSE WHEN
A small number of entities share the same normalized measures.
AVOID WHEN
Precise comparison or more than eight dimensions is required.

SEMANTIC RULES
- Use identical scales or normalize values.
- Limit overlapping profiles.
- State whether area has meaning—it usually does not.
QUESTIONS IT ANSWERS
- How do profiles differ?
- Where is each option strong or weak?
