This bar chart displays the population of the top 10 most populous countries, using 2018 estimates from the UN World Population Prospects. The chart renders as SVG with a light blue background, showing each country on the y-axis and its population on the x-axis. The code uses D3 v7 modules including `select`, `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to load the data, scale the values, and draw the axes. Bars are appended as rectangles with steelblue fills, and population values are multiplied by 1000 from the CSV source.
