This scatter plot displays the relationship between billionaire rank and final worth, with each circle colored by industry category. The visualization uses D3.js v6 to load CSV data from a GitHub gist and render SVG elements. It employs `d3.scaleLinear` for both axes, `d3.scaleOrdinal` with `d3.schemeCategory10` for categorical coloring, and `d3.axisBottom`/`d3.axisLeft` for labeled axes. Interactive tooltips appear on mouseover, showing each person’s name, worth, category, and age.
