This bar chart displays the populations of the world’s ten most populous countries, from China down to Mexico, with horizontal bars sized by population. The visualization uses D3 v5’s `scaleLinear` and `scaleBand` to map data values to positions, and `axisLeft` and `axisBottom` for the country and population axes. It loads data from a CSV file, converts population figures, and animates bar growth via `transition`. The chart is rendered as SVG within a React project, with styling controlled by an external stylesheet.
