This bar chart displays the populations of the top 10 most populous countries, with data from the 2018 United Nations World Population Prospects estimate. The chart uses a linear scale for population on the x-axis and a band scale for country names on the y-axis, with steelblue rectangles as bars. The visualization is rendered as SVG using D3 v5, employing `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to construct the plot.
