This example shows a horizontal bar chart of country populations using a CSV data file with population values scaled by 1,000. The visualization builds the chart with D3 v5, employing `d3.csv` for data loading, `scaleLinear` and `scaleBand` for positioning, and `axisLeft` and `axisBottom` for axes. Rectangles are appended to an SVG group and styled with steelblue fills. The rendering relies on SVG elements, with margins calculated from the chart’s dimensions to place the visualization properly.
