This bar chart visualizes the populations of the ten most populous countries, based on 2018 estimates from the United Nations World Population Prospects. It uses D3 v5 to create an SVG with linear and band scales, displaying horizontal bars labeled by country. The chart’s axes are generated with `axisLeft` and `axisBottom`, while data is loaded from a CSV file and rendered as `rect` elements filled with steelblue, with a title added as a text element.
