This visualization presents a horizontal bar chart of country populations, ranking nations from China to Mexico. It demonstrates how to load external CSV data and convert it into a visual form. Using D3 v5, the code employs `select`, `csv`, `scaleLinear`, `scaleBand`, and `max` to parse the data file, transform population values from thousands to raw counts, and map them to bar lengths. The SVG rendering scales the bands to fit the fixed canvas dimensions.
