Customizing Axes
This example visualizes the top 10 most populous countries using a horizontal bar chart, with population values from the 2018 United Nations World Population Prospects. The chart customizes D3 axes by removing domain lines, formatting population tick labels to abbreviate billions with ‘B’, and adding a custom axis title. The code uses d3.scaleLinear, d3.scaleBand, d3.axisBottom, and d3.axisLeft to render the SVG visualization, styling elements via CSS.
