This visualization displays the populations of 30 countries in 2020 as horizontal bars, ranked by country name along the vertical axis. The bars use a light green fill, with blue axis ticks and gray labels, and a title reading “POPULATION-2020” labels the x-axis. Built with React and D3 v5, it uses `scaleBand` and `scaleLinear` to map data, `csv` to load the dataset from GitHub, and renders the chart as SVG. Hovering over a bar shows a tooltip with the population value formatted using D3’s `format` function.
