Radar Chart Maker — Free Spider & Web Charts

In short: the Radar Chart Maker spreads your categories around a circle and plots each series as a polygon — the fastest way to compare overall profiles and spot strengths and gaps.

Player stats, skill self-assessments, product comparisons across features: a radar turns a table of scores into a shape you can judge in seconds.

Private by design: everything in this tool happens 100% in your browser with JavaScript. Your data, photos and designs are never uploaded to a server, never stored and never seen by us - close the tab and everything is gone.

How to use the Radar Chart Maker

  1. Type your labels and numbers into the grid, or paste CSV into the box below the chart and press Apply CSV.
  2. Adjust the title, legend and per-series colours until the chart reads clearly at a glance.
  3. Press Download chart as PNG and drop the image into your document, slides or post. Use Copy my data as CSV to save your figures for later.

How it works

Every category gets an axis from the centre; a value’s distance along its axis is proportional to the value against a rounded maximum. Series polygons are drawn with a translucent fill so overlaps stay visible. The chart is drawn by hand on an HTML canvas by Loona’s shared chart engine — no chart library and no server. Everything is computed locally, so your numbers never leave your device.

Worked example

A coach compares two players across five attributes. Player A’s polygon bulges on Teamwork, Player B’s on Power — selection for the next match gets easier.

Frequently Asked Questions

How many attributes work well?

Five to eight axes read best. Scores should share one scale (for example 0–10) so shapes compare fairly.

Can I compare two profiles?

Yes — add a second series; its polygon overlays the first in its own colour.

What if my scales differ?

Normalise first (for example convert each attribute to a 0–10 score) so no axis dominates unfairly.

Is my data uploaded?

No — drawn entirely in your browser.
