This fork bar chart displays population data for 15 countries from the United Nations World Population Prospects 2019, using horizontal bars ranked by value against a linear scale. The visualization is built with React and d3-v5, leveraging `scaleBand` for the categorical y-axis, `scaleLinear` for the numerical x-axis, and SVG rectangles to encode population sizes. Data is loaded via d3’s `csv` method, and the chart includes a loading state rendered as text before the data arrives.
