A pie chart displays the distribution of penguin species from a CSV dataset, showing counts for each species with labeled segments. The visualization uses D3 v6 APIs including `d3.csv` for data loading, `d3.pie` and `d3.arc` for generating the pie geometry, and `d3.scaleOrdinal` with `schemeCategory10` for colors. Each segment is rendered as an SVG path with a white stroke, and text labels using `arcPath.centroid` position the species name and count at the center of each slice.
