This example shows a horizontal bar chart of country populations using SVG shapes styled with CSS. The bars are drawn as `rect` elements with a pink fill, and the chart includes axes rendered via D3’s `scaleLinear`, `scaleBand`, `axisBottom`, and `axisLeft`. Population values from a CSV file are loaded with `csv()` and scaled against the chart’s width, while `selectAll` and data joins append the rectangles. The code relies on D3 v5 and SVG, with CSS controlling font size and rectangle color.
