This example shows a pie chart of flower species counts from a CSV dataset, with hover tooltips displaying each species’ label and value. The visualization is built using D3.js, leveraging the `pie` and `arc` generators to compute and draw the slices, and `schemeCategory10` for coloring. The SVG renders at full window size, and a legend notes each species by color, while the data is loaded asynchronously via `d3.csv`.
