This example shows a horizontal bar chart ranking the 23 most populated U.S. counties, with each bar labeled with its exact population count. The visualization uses React with D3 v5, employing `scaleLinear` for the x-axis and `scaleBand` for the y-axis, with `axisLeft` and `axisBottom` for ticks. Data from the CSV file is loaded via `csv()`, and bars are rendered as SVG `<rect>` elements. The chart includes a title, axis label, and a fixed 900×500 SVG canvas.
