This visualization displays the top 10 countries by year 2000 population as a horizontal bar chart. The chart uses React components to render SVG rects scaled by a linear population scale, with country names on a band scale. Data is loaded from a remote CSV using d3.csv and formatted with the d3.format function to abbreviate large numbers. The axes are built with custom React components that map d3.scaleLinear and d3.scaleBand outputs to SVG elements.
