This chart displays real survey data as a radar chart with four axes representing Community, Self-expression, Discovery, and Agency. Twelve social media platforms are plotted as irregular, outlined shapes, each color-coded to match a custom legend built with D3 scale-chromatic. The visualization uses `d3.scaleLinear` for each axis, `d3.line` to generate closed paths, and D3's selection and join methods to construct the axes, labels, and legend. The data is fetched from a remote CSV and grouped and averaged using `d3.group` and `d3.mean`.
