This chart displays the population figures for 30 countries in 2020. Built with React and D3 v5, it renders as an SVG with a horizontal bar chart layout. Each bar’s length is scaled using `scaleLinear`, with country names positioned via `scaleBand`. The visualization uses D3’s `csv` loader to fetch data from a remote GitHub dataset, and axis formatting is applied with D3’s `format` function to abbreviate large numbers.
