This example displays a horizontal bar chart comparing the populations of ten countries in the year 2000, sourced from a CSV file. Using React with D3 v5, it employs `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis, rendering bars as SVG rectangles. Population values are formatted using `format` to abbreviate large numbers, and hovering reveals exact values via SVG `<title>` elements.
