This example displays the world population in 2016 for 24 countries as horizontal bars, sorted by population size. Using D3 v5, the code loads data from a CSV file and renders an SVG bar chart with custom axes. The y-axis uses `scaleBand` for country names, while the x-axis uses `scaleLinear` with custom tick formatting via `format('.3s')` to abbreviate numbers, and grid lines are drawn with `axisBottom` and `tickSize`.
