Customizing Axes
This bar chart displays the top 10 most populous countries based on 2018 United Nations estimates, using population values multiplied by 1000. The visualization emphasizes customized axes: the left axis removes domain and tick lines, while the bottom axis uses a tick format that converts gigabytes to billions. Built with D3 v5, it employs `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to render the SVG chart, with styled tick text, axis labels, and a title defined in CSS.
