Overview
Also known as a spider chart or web chart, radar charts are used to compare multiple quantitative variables across different categories. They are particularly useful for showing 'profiles' or 'signatures' (e.g., comparing the skills of different job candidates).
Challenges
- Can become cluttered and hard to read with too many categories.
- The area of the shape can be misleading as it depends on the order of the axes.
- Hard to compare values accurately across different axes.
Use Cases
- Comparing product features.
- Visualizing athlete performance metrics.
