This visualization displays the species distribution of the Palmer Penguins dataset as a stylized, animated 3D-effect pie chart. Using D3.js v7, it loads data from a CSV file and aggregates counts by species with `d3.rollup`. Pie slices are drawn with `d3.pie` and `d3.arc`, featuring linear gradients, animated entrance via `transition.attrTween`, and hover expansion effects. Connector lines and labels are added using `outerArc.centroid`, with the SVG rendered on a card-style background featuring drop shadows.
