This radar chart visualizes institutional characteristics across four axes: total enrollment, endowment per student, annual R&D expenditure, and undergraduate selectivity. Each social media presence is represented as a colored polygon, with interactive legend items and hover highlighting to isolate specific platforms. Users can click legend entries to toggle visibility. Built with D3 v7, the visualization uses scaleLinear for axes, line for path construction, and custom event handlers for mouseover interactions, fetching data from a remote CSV source.
