This bar chart displays the population of the top 10 most populous countries, with China and India leading by a significant margin. The visualization uses D3 v5’s `scaleLinear` for the x-axis and `scaleBand` for the y-axis, rendering SVG rectangles. Data comes from the World Population Prospect 2017, with raw values multiplied by 1000. The chart includes formatted tick labels via `axisBottom` with a custom `.3s` format, a population axis label, and a title, all styled with tomato-colored bars and a Ubuntu font.
