Customizing Axes
This bar chart displays the population of the top 10 most populous countries using 2018 United Nations estimates from a CSV file, with labels converted from millions to billions. It demonstrates customized D3 axes, including a horizontal axis with tick formatting and vertical grid lines, while the horizontal axis label and title are added as SVG text. The visualization uses D3 v5’s `scaleLinear`, `scaleBand`, `axisBottom`, and `axisLeft`, and animates rectangle widths via `transition()` over two seconds, with data loaded via `csv` and formatting via `format`.
