This scatter plot visualizes the rank and final worth of billionaires, using color to distinguish their industry categories. Built with D3 v6, it renders circles as SVG elements, with axes for rank and final worth in billion dollars. The code employs `d3.scaleLinear` for both axes and `d3.scaleOrdinal` with `d3.schemeCategory10` for categorical coloring. Hovering reveals a tooltip with the individual's name, worth, category, and age. Data is loaded asynchronously via `d3.csv` from a GitHub-hosted CSV file.
