This interactive bar chart displays the top 10 most populous countries using a dataset of cancer statistics, though the code loads 53 rows. The visualization is built with React and D3 v5, using D3's `scaleBand` and `scaleLinear` to map country names and population values to SVG rectangles. The rendering leverages React's declarative components to generate SVG elements, with axes and tick marks created through D3's `ticks()` method. Data is loaded asynchronously via D3's `csv()` function from a GitHub gist URL.
