This bar chart visualizes population data for ten countries loaded from a local CSV file, displaying each country’s population as a vertical rectangle. The chart uses D3 v5’s `scaleBand` for the categorical x-axis and `scaleLinear` for the numeric y-axis, with SVG rendering. Axes are not drawn, but the bar heights are set via the y-scale, and the data values are multiplied by 1,000. The example demonstrates ES6 module imports for D3 functions and local modules, with data loaded asynchronously via `csv()`.
