This example demonstrates how to customize axis elements in a bar chart, showing population figures for ten countries from a CSV file. The chart uses SVG rendering via D3 v5, with `d3.select` to attach the visualization to an SVG container. The axes are styled and positioned using D3’s scale and axis functions, while the data is loaded asynchronously with `d3.csv`. The minimal CSS keeps the page clean, and the chart focuses on readable, annotated axes.
