This example demonstrates how to customize chart axes in a horizontal bar chart showing the populations of the top ten most populous countries. It uses D3 version 5 to load data from a CSV file and render SVG graphics. The code applies custom tick formatting with `d3.format`, removes default axis domain lines and tick lines, and adds labels for the x-axis and chart title. The y-axis uses `d3.scaleBand`, while the x-axis uses `d3.scaleLinear`.
