This bar chart displays the population of the ten most populous countries using 2018 estimates from the UN World Population Prospects. The visualization employs D3.js v6 with SVG rendering, using `scaleLinear` for the x-axis and `scaleBand` for categorical country labels. Population values, read from a CSV file via D3's `csv` method, are multiplied by 1000 before being drawn as steelblue rectangles with axes generated by `axisLeft` and `axisBottom`.
