This radar chart visualizes survey data mapping social media platforms across four dimensions: Community, Self-expression, Discovery, and Agency. The D3.js v7 visualization renders each platform as a diamond-shaped path on a square radar layout with four linear axes. Interactive features include hover highlighting that emphasizes corresponding legend items and radar shapes, plus clickable legend entries that toggle platform visibility. Data originates from a CSV file parsed with d3.csvParse and aggregated using d3.group and d3.mean to compute average scores per platform.
