data visualization
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 uses D3 v5 with SVG rendering, featuring customized axes through the `d3.axisBottom` and `d3.axisLeft` APIs, along with styled tick marks and labels. The chart builds on a basic bar chart example by enhancing axis customization, such as adjusting font sizes, colors, and gridlines through CSS classes applied to D3-generated elements. The data is loaded from a CSV file using `d3.csv`.
