This example shows a horizontal bar chart of UN population data for various countries, rendered as SVG elements using React. The chart maps country names to the y-axis with d3.scaleBand and uses d3.scaleLinear for the x-axis based on population values, though the width encoding is incomplete. Data is loaded asynchronously with d3.csv from a remote URL, and React’s useState and useEffect manage the fetch and render cycle. The visualization highlights a hybrid approach, combining D3’s data-loading and scaling utilities with React’s component-based DOM updates.
