A pie chart displays the number of followers, in millions, for the top eight Instagram accounts, including Instagram, Cristiano Ronaldo, and Lionel Messi. The visualization uses D3.js version 5 and 6 to load CSV data, generate the pie layout with `d3.pie()` and `d3.arc()`, and color each segment via `scaleOrdinal`. Text labels with follower counts are positioned using arc centroids, while a legend lists account names and values. The chart renders as SVG with a vibrant gradient background.
