This pie chart visualizes average hours spent per week on various social media platforms, sourced from a CSV file loaded with `d3.csv`. It uses `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate the SVG slices and a color scale. Labels and connector polylines are positioned via `arc.centroid` and `outerArc.centroid`. Clicking a slice updates an HTML div with platform-specific details, while a legend lists all platforms.
