This pie chart visualizes drug satisfaction survey results, with each slice representing a drug and its corresponding satisfaction percentage. The chart uses D3.js v5 to load CSV data from a Gist URL via `d3.csv`, render the pie using `d3.pie` and `d3.arc`, and color segments with `d3.scaleOrdinal`. A legend lists drug names and computed percentages, formatted with `d3.format` to five significant digits. The SVG output is interactive in layout but static in behavior, with all elements positioned explicitly.
