This example presents a horizontal bar chart of the top 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects. The visualization highlights customized axes, including a band scale for country names on the y-axis and a linear scale for population on the x-axis. The code uses D3 v7 APIs such as `scaleLinear`, `scaleBand`, `axisBottom`, and `axisLeft`, with the x-axis labels formatted using `format('.3s')` to abbreviate large numbers. SVG rendering is used to draw the bars, with a title and axis label included.
