This visualization shows a horizontal bar chart of categorical data, where bar lengths are proportional to numeric values. Built with React and D3 v5, it uses `scaleBand` for the y-axis categories and `scaleLinear` for the x-axis values, rendering bars as SVG rectangles. The chart includes formatted tick labels (converting large numbers to abbreviations like “B” for billions), axis labels, and tooltips showing exact values on hover. Data is loaded from an external CSV source via D3’s `csv` function, with the first ten rows displayed.
