This bar chart displays the population of the top 10 most populous countries using 2018 estimates from the United Nations World Population Prospects. The visualization customizes both axes: the y-axis removes tick lines and domain, while the x-axis uses a `format('.3s')` tick formatter to abbreviate values and adds a custom “Population” label. Built with d3.v5, it uses `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to render SVG rectangles.
