A horizontal bar chart compares the average worth of billionaires by inheritance type, using a band scale for categorical labels and a linear scale for worth values. Built with D3 v7, the SVG visualization reads data from a remote CSV file containing billionaire statistics. The code demonstrates the `d3.csv` data-loading method, `d3.scaleBand` and `d3.scaleLinear` for axes, and `d3.axisLeft`/`d3.axisBottom` to render gridlines and tick marks. Each rectangle's height and width derive from the scales, with steelblue fill styling applied via CSS.
