This bar chart displays population figures for ten countries, from China at over 1.4 billion down to Mexico at 130 million. The visualization uses D3 v5 with a promise-based data-loading pattern, where `csv` fetches `data.csv` and multiplies each population value by 1,000. The SVG rendering employs `scaleLinear` and `scaleBand` for axes, with `axisBottom` and `axisLeft` to draw ticks and gridlines. The chart formats population labels as abbreviated values with a custom tick formatter that replaces "G" with "B", and removes the domain lines for a cleaner look.
