Radar charts (also called spider or web charts) plot multiple quantitative variables on axes starting from the same center point, forming a polygon shape. They excel at comparing multi-dimensional profiles, such as skill assessments, product feature comparisons, and performance evaluations. viz42 generates radar charts from dimension descriptions, creating balanced, readable multi-axis visualizations.
Mermaid does not have a native radar/spider chart type. viz42 generates an approximation using labeled nodes, and the visual canvas renders the multi-axis radar layout.
Radar charts are most effective with 5-8 dimensions. Fewer than 5 looks sparse; more than 10 becomes hard to read. Group or average metrics if you have too many.
Yes. Describe as many items as you want to compare, each with scores on the same dimensions. viz42 will overlay the polygons for visual comparison.
