This example displays a horizontal bar chart ranking the populations of up to 30 countries for the year 2020, using green bars with blue axis ticks. The visualization is rendered as an SVG within a React application, leveraging D3 v5 methods such as `scaleBand`, `scaleLinear`, and `csv` to fetch and format data from a remote GitHub dataset. The code demonstrates modular imports from D3 and local ES6 modules, and tooltips appear on hover via a `<title>` element.
