This bar chart displays the 2018 population estimates for the top 10 most populous countries, sourced from the United Nations World Population Prospects. Using D3 v5, it renders an SVG with horizontal bars sorted by country name, a formatted x-axis that abbreviates large numbers (e.g., "B" for billions), and a custom title. The code applies `d3.scaleLinear`, `d3.scaleBand`, `d3.axisLeft`, and `d3.axisBottom`, with data loaded via `d3.csv` and scales configured inside the `render` function.
