This example shows a horizontal bar chart of country populations using D3 v5, with a custom-styled y-axis and numeric labels for each bar. The chart loads population data from a CSV file, scales the values to a linear x-axis and a banded y-axis, and renders filled steel-blue rectangles via SVG. It uses `d3.csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom`, with margins and a translated group element to position the axes and bars.
