This visualization displays a bar chart of the top 10 most populous countries using 2018 population estimates from the United Nations World Population Prospects. The chart demonstrates customized D3 axes, including rotated tick labels and styled tick lines. It uses D3 v5’s `scaleBand` for the categorical country axis and `scaleLinear` for the population axis, with `axisBottom` and `axisLeft` to render the axes. The bars are SVG rectangles, and the layout applies margins with explicit positioning for the axis labels and title.
