This bar chart shows the top 10 most populous countries from the 2018 United Nations population estimates. It demonstrates customized D3 axes, with a bottom axis formatted using `format('.3s')` to abbreviate large population numbers, and a left axis stripped of its line and domain. The chart uses `scaleLinear` for population and `scaleBand` for country names, with tick lines spanning the full inner height. The data comes from a CSV file loaded via `csv('data.csv')`, and the chart is rendered as SVG.
