This bar chart shows the top 10 most populous countries, with horizontal bars representing each nation's population. Population values are read from a CSV file and scaled using `scaleLinear`, while country names are positioned on the y-axis with `scaleBand`. The visualization uses D3 v5, with axes rendered via `axisLeft` and `axisBottom`, and the overall layout draws inside an SVG canvas. Data is loaded asynchronously using the `csv` method, and bars are styled with the `rect` element.
