This example shows a bar chart of population values for a list of countries, with each bar’s length scaled linearly and countries arranged along a categorical band scale. It uses D3 v5 with SVG rendering, applying `d3.scaleLinear` and `d3.scaleBand` to map data to positions, and `d3.axisLeft` and `d3.axisBottom` for the axes. Data is loaded from a CSV file via `d3.csv`, and population figures are parsed and multiplied before rendering.
