This example shows the populations of ten countries in the year 2000 as a horizontal bar chart, with country names on the y-axis and population counts on the x-axis. The visualization uses React to render SVG elements, with d3.scaleBand and d3.scaleLinear for the axes and d3.format to abbreviate tick labels (e.g., converting billions). Data is loaded from a remote CSV file via d3.csv, filtered to the first ten rows, and displayed as gray rectangles with tooltips showing the formatted population value.
