This example displays the populations of the top 10 most populous countries using a horizontal bar chart with SVG rendering. The chart customizes D3 axes by removing domain lines and tick marks, formatting population values with abbreviations (e.g., "B" for billions) via `d3.format`, and adding axis labels and a title. Data is loaded from a CSV file using `d3.csv`, and scales are created with `d3.scaleLinear` and `d3.scaleBand`. Source data comes from the 2018 United Nations World Population Prospects estimate.
