Radar Chart
Radar charts (also known as spider charts or web charts) represent multivariate data on axes starting from the same point and extending outward. Each axis represents a different variable, and data points are plotted along each axis and connected to form a polygon. This allows for easy comparison of multiple variables across different categories or observations.

Examples
Comparison of product attributes across multiple dimensions
Chart Visualization
This example includes an interactive chart visualization with 3 data points.
Chart type: radar
Usage
Best Used For
- Comparing multiple variables across different categories simultaneously
- Visualizing performance metrics or attributes across multiple dimensions
- Identifying patterns, outliers, or imbalances across variables
- Comparing the 'profiles' of different entities across the same set of metrics
Data Requirements
[Object]
Limitations
Important Considerations
- ⚠Can be misleading if axes aren't properly scaled or normalized
- ⚠Becomes cluttered and difficult to interpret with too many variables or categories
- ⚠Area size can visually overemphasize differences in outer variables
- ⚠Difficult to precisely compare specific values between different categories
