This example displays the top 10 most populous countries as a horizontal bar chart using React and SVG. It loads population data from a CSV file via `d3.csv`, scales the bars with `d3.scaleLinear` and the country names with `d3.scaleBand`, and formats axis ticks using `d3.format`. The chart includes styled axes, a population label, and tooltips rendered through SVG `<title>` elements.
