This bar chart displays population estimates for six global regions in 2019, with horizontal bars ordered by region name. The visualization uses D3 v5 with SVG rendering, leveraging `scaleLinear` for the population axis and `scaleBand` for categorical region placement. Data is loaded from a CSV file via `d3.csv`, and population values are multiplied by 1000 before mapping to bar widths. Axes are generated with `axisLeft` and `axisBottom`, while rectangles represent each region’s population, styled with steelblue fill.
