This bar chart displays the population of the top 10 most populous countries, based on 2018 estimates from the United Nations World Population Prospects 2017. The visualization uses D3 v5’s `scaleLinear` for the x-axis and `scaleBand` for the categorical y-axis, with `axisLeft` and `axisBottom` to render the axes. Rects are appended to an SVG group, sized by population values loaded from a CSV file. The chart also demonstrates custom axis styling through CSS.
