This example demonstrates a bar chart that displays the top ten countries by population for the year 2020, sourced from a CSV file by Curran. The visualization is built using React for component structure and D3.js for scaling and rendering, with the chart drawn as SVG rectangles. The code uses D3's `csv` parser to load data, `scaleBand` for the categorical y-axis, and `scaleLinear` for the quantitative x-axis.
