This example presents a horizontal bar chart of the 2020 populations for 11 countries, sorted by a pre-defined order. It is rendered as an SVG using React components, with D3.js (v5) handling the scale computations: `scaleBand` for the categorical country axis and `scaleLinear` for the population axis. The visual styling uses a custom Poppins font, a teal color for bars, and grey for tick labels. D3’s CSV loader fetches the data from a gist, and tooltips display formatted values like “1.23B”.
