Free local tool

Radar Chart Maker

Compare multivariate scores in a bounded radar or spider chart with one shared scale and an accessible data table.

Private by design: inputs and local files stay in this browser tab. The tool sends no input to a server and stores nothing after the page closes.

JavaScript is required for the interactive tool.

Method and limits

Supports 3-12 unique axes, 1-8 series, and one explicit shared finite scale. Values outside the scale are rejected rather than clamped. Labels are inserted only as text. SVG export is not included in V1.
