What is a Radar Chart?
A radar chart — also called a spider chart or web chart — plots multiple variables on axes radiating from a center point, connecting them to form a polygon shape. Each axis represents a distinct category, such as speed, cost, or quality, making it easy to compare the overall profile of one or more subjects at a glance. Use a radar chart when you need to evaluate several dimensions simultaneously and quickly spot strengths, weaknesses, or imbalances across a consistent scale.

When to Use
- You are comparing 3–8 attributes for one or more subjects
- You want a visual profile to show overall balance or imbalance
- All axes share a common scale or can be normalized to one
- You need to highlight gaps across dimensions at a glance
- A grouped bar chart would require too many columns to be readable
Common Mistakes
- Using more than 8 axes — too many spokes make the chart unreadable
- Overlaying more than 3–4 series — they overlap and obscure each other
- Mixing axes with different scales without normalizing to a common range
- Including unrelated categories that don't belong in the same profile
- Treating filled area size as a meaningful metric — polygon area can mislead
- Leaving axis labels vague, making readers guess what each spoke represents
