Customizing Axes
A horizontal bar chart displays the top 10 most populous countries, with population values scaled by 1,000 and formatted in billions. D3 v5’s `scaleLinear` and `scaleBand` position bars, while `axisLeft` and `axisBottom` render axes with custom tick formatting via `format('.3s')`. The SVG chart removes default axis lines and domain strokes, styling ticks and labels through CSS. Data loads from a CSV file using `csv`, and margins define the plotting area.
