This pie chart visualizes the species distribution within the Palmer Penguins dataset. The chart displays proportional slices for each species, colored via a categorical scale, with labels and a legend for identification. Built with D3.js, the visualization uses `d3.pie` to compute arc segments and an SVG `path` generator to render them. Data is loaded asynchronously from a CSV hosted on GitHub, and counts are aggregated using `d3.group`. The rendering relies on SVG shapes and text elements.
