This visualization displays populations of ten countries in the year 2000 as a horizontal bar chart rendered with SVG in React. It uses D3’s scaleBand for the categorical y-axis, scaleLinear for the quantitative x-axis, and format for truncated tick labels (e.g., 'B' for billions). Data is loaded via d3.csv from a GitHub-hosted CSV file, with population values multiplied by 1,000. Tooltips show formatted population values via SVG <title> elements, and axis ticks are styled with blue lines and gray text.
