A horizontal bar chart displays population data for ten countries, with bars extending from the left edge and country labels on the y-axis. The example emphasizes customizing axes by styling the bar lengths and band spacing without visible tick marks or labels. It loads data from a CSV file using `d3.csv`, transforms population values by multiplying them by 1000, and renders SVG rectangles with `d3.scaleBand` for the categorical y-axis and `d3.scaleLinear` for the numeric x-axis. The chart adapts to the SVG’s width and height attributes.
