This bar chart displays the populations of the ten most populous countries, based on 2018 estimates from the United Nations' World Population Prospects. It uses D3 v5 APIs including `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to load data, map values to positions, and render axes as SVG. Population values are multiplied by 1000 and represented as horizontal bars, with country names on the y-axis and population on the x-axis. The chart is styled with steelblue rectangles and larger text for readability.
