Customizing Axes
This bar chart shows the population of the top 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects. The visualization demonstrates customized D3 axes, including tick labels formatted with `d3.format`, a removed domain line, and an added axis label. It uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis, and `d3.axisBottom` and `d3.axisLeft` to render the axes in SVG.
