This example displays a horizontal bar chart of population figures for 30 countries in 2020, sourced from a GitHub-hosted CSV file. The React-based visualization uses D3 v5’s `scaleBand` and `scaleLinear` to map country names and population values to SVG rectangles, with custom `AxisBottom` and `AxisLeft` components rendering ticks. A tooltip on each bar reveals the exact population, formatted using D3’s `format` function, while green marks and styled axes highlight the data. The chart is rendered entirely as SVG within a React component.
