Radar Chart Maker is a free, independent tool for building radar charts (also called spider charts or web charts) — you enter labeled data points, it draws the chart live using real polar geometry, entirely in your browser. No account, no upload, no cost.
We're an independent maker of small, single-purpose web tools — sites built to do one job well rather than bundle a dozen half-finished features. Radar Chart Maker is one tool in that family, focused specifically on comparison and skill/attribute visualization.
You enter axis labels (categories) and a numeric value per axis for one or more datasets. The tool places each axis evenly around a circle, scales each value against either an auto-detected or manual maximum, and connects the resulting points into a polygon per dataset — the standard radar-chart construction. Editing any label, value, color, or dataset name redraws the chart immediately. When you're happy with it, export a PNG or SVG file directly from your browser.
Anyone comparing several things across the same set of criteria: product or vendor comparisons, skill/attribute charts for games or characters, performance-review competency charts, or survey results broken out by category.
Every chart is built and rendered entirely on your own device using inline SVG — nothing is uploaded to, or stored on, our servers. See the full privacy policy for details.
