This example shows a pie chart of population data for ten countries, drawn as SVG arcs with percentage labels and a legend. The visualization is built using React and D3 version 5, leveraging the `pie` and `arc` functions to compute arc segments and `schemeCategory10` for color encoding. Data is loaded from a remote CSV file using `d3.csv`, with population values scaled by ten, and labels are formatted as percentages. The chart includes axis labels, although the implementation mixes pie and bar chart styling, creating a hybrid visual.
