This bar chart displays the population of the world’s ten most populous countries using 2018 estimates from the United Nations’ World Population Prospects. It uses D3 v5 with `csv`, `scaleLinear`, `scaleBand`, `axisBottom`, and `axisLeft`, rendering to SVG. The chart customizes axes by removing domain lines, adding gridlines, applying tick formatting with `format('.3s')` and replacing “G” with “B”, and appending a custom axis label and title.
