This pie chart displays the percentage breakdown of weekly time allocation across categories. Each slice is labeled with its corresponding activity name and percentage, connected by leader lines, with a legend on the right showing hours per category. The visualization uses d3.pie and d3.arc to generate slices, d3.csv to load remote data with d3.autoType, and d3.scaleOrdinal with d3.schemeCategory10 for colors. It renders as SVG, with polylines for leader lines and text elements for labels.
