Customizing Axes
This bar chart displays the top 10 most populous countries in 2018, using data from the United Nations World Population Prospects. It shows population values on the x-axis and country names on the y-axis. The example demonstrates D3 axis customization, including formatted tick labels that abbreviate numbers with "B" for billions and removed axis lines. It uses d3.csv, d3.scaleLinear, d3.scaleBand, d3.axisBottom, and d3.axisLeft to render the SVG visualization, with custom styling applied to ticks and labels.
