This example displays the populations of the ten most populous countries using a horizontal bar chart. The y-axis labels are customized with a distinct color and the axis lines removed, while the x-axis uses tick marks that span the chart’s height and formats values in abbreviated notation via `format('.3s')`. Data is loaded from a CSV file and processed with `csv()`, then scaled using `scaleLinear` and `scaleBand` from D3 v5. The chart is rendered as SVG elements, with axis labels and bars styled through external CSS.
