Customizing Axes
This example shows a horizontal bar chart of the top 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects. It builds on a basic bar chart by customizing the D3 axes, removing default tick lines, and reformatting population values with abbreviations like "B" for billions. The code uses D3 v5 APIs such as `scaleLinear`, `scaleBand`, `axisBottom`, and `axisLeft`, rendering to SVG. Population data is loaded from a CSV file and multiplied by 1000 to reflect actual values.
