This radar chart visualizes survey responses grouped by media type, with each axis representing a human participant and values reflecting mean point scores. The fork adds interactive legend toggling that hides or dims radar shapes, plus hover highlighting that thickens the selected shape’s stroke and bolds the matching legend item. Built with D3 v7, it uses `d3.group`, `d3.mean`, and `d3.csvParse` for data processing, and CSS classes control opacity and display states for unchecked items. Data loads from a remote CSV, and the chart renders as an SVG with a square, bordered layout.
