This bar chart displays the population of 10 countries in the year 2000, ordered along a vertical band scale with horizontal bars extending from a shared origin. The visualization uses React with d3-scale’s `scaleBand` and `scaleLinear` to map country names and population values, while custom React components render SVG axes and marks. Population values are loaded from a CSV file, scaled using d3-format’s `format('.2s')` to abbreviate tick labels (e.g., ’B’ for billions), and exposed via native SVG `<title>` tooltips. Styling applies blue tick lines, light green bars, and a Poppins font.
