This bar chart displays the population of the top 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects. The example demonstrates customizing D3 v5 axes, including removing axis domain lines and tick lines from the y-axis, formatting x-axis tick labels with the `format` function, and adding custom axis labels and a title. Data is loaded from a CSV file and rendered as SVG rect elements, with scales created using `scaleLinear` and `scaleBand`.
