An interactive scatter plot of the salaries dataset explores relationships among academic salary, years since PhD, and years of service using React and D3. Users select X and Y axes and filter data by rank, discipline, or sex through dropdowns. Hovering over the color legend highlights points matching that category, while other points fade. The visualization uses d3.scaleLinear scales, d3.scaleOrdinal color encoding, and crossfilter for data manipulation, rendering circles via SVG.
