This bar chart displays the ten most populous countries, with each bar representing a country’s population. The visualization uses React to render SVG elements, leveraging d3-scale functions like `scaleBand` and `scaleLinear` to position bars and axes. Data comes from the United Nations World Population Prospects 2019, loaded via `d3.csv`. The chart applies a custom Poppins font, teal bar fills, and formatted tick labels that convert values from gigabytes to billions.
