This visualization presents a scatter plot of billionaire data, mapping each individual’s rank along the x-axis against their final worth in billion dollars on the y-axis. Circles are colored by category, with a tooltip revealing the person’s name, worth, category, and age on hover. Built with D3 v6, it loads a CSV from a gist, uses `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `d3.scaleOrdinal` with `d3.schemeCategory10` for colors. The SVG rendering includes labeled axes and interactive mouseover events.
