This example shows a horizontal bar chart of the ten most populous countries, using a React component that loads data from a CSV via `d3.csv`, scales population values with `d3.scaleLinear`, and positions country labels with `d3.scaleBand`. The SVG rendering includes axis components built with `d3` tick marks and text, while each bar is a `rect` element with a `title` tooltip that formats population figures using `d3.format`. Styling is applied via CSS classes for ticks and marks.
