This bar chart displays the population of the top 10 most populous countries from the 2018 United Nations World Population Prospects estimate, with each bar’s length scaled by population and countries listed on the y-axis. The visualization uses D3 v5’s `csv` loader to parse the data, `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `axisBottom` with custom tick formatting (e.g., converting billions to "B") and a population axis label. It renders to SVG, with a title, removed axis domain lines, and steelblue bars.
