This example visualizes population data for ten countries as a bar chart, with counts adjusted by a factor of one thousand. Built with D3 v5, it uses `select`, `csv`, `scaleLinear`, `scaleBand`, `max`, `axisBottom`, `axisLeft`, and `format` to render SVG elements. The chart draws steelblue bars and labels each with its population value, while comments indicate optional axes and gridlines that are currently disabled.
