This pie chart visualizes survey responses about people’s preferred social media platforms, displaying each category’s percentage share. The chart uses D3.js v5 with SVG rendering, fetching CSV data via `d3.csv` and constructing arcs with `d3.pie()` and `d3.arc()`. Each slice is labeled with its percentage, and a legend lists the platform names alongside color swatches and values. Colors are assigned using `d3.scaleOrdinal`, while text formatting relies on `d3.format`.
