This bar chart displays population figures for ten countries and political unions, using horizontal bars to compare values from China to Russia. The visualization relies on D3 v7’s `scaleLinear` and `scaleBand` to map population counts and country names, while `axisLeft` and `axisBottom` generate the axes. Data is loaded from a CSV file via `d3.csv`, and the SVG rendering applies a steelblue fill to each rectangle bar.
