A bar chart displays the population of the top 10 most populous countries using 2018 estimates from the United Nations’ World Population Prospects 2017. The chart uses D3 v5’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to render the bars, with axes customized to remove domain lines and format population ticks in billions. SVGs are generated dynamically via `csv()` loaded data, and the chart includes a title and x-axis label.
