This radar chart visualization compares social media platforms across four dimensions: Community, Self-expression, Discovery, and Agency. Users hover over a platform's radar shape or legend item to highlight it, dimming all other shapes to focus on the selected media. Legend items can be clicked to toggle a platform's visibility entirely, removing it from the chart. The visualization uses D3 v7's `scaleLinear` for axes and the `line` function for path generation, with custom hover and legend interaction logic built using `d3.select` and event handlers. Data is fetched as a CSV and processed using `csvParse` and `d3.group` to compute mean scores per platform.
