This pie chart visualizes temperature distribution across cities from an online food orders dataset, categorizing temperatures into low, medium, and high ranges. The chart uses a standard D3 pie layout with colored arcs and labels, displaying category names directly on the slices. A legend with matching color swatches appears beneath the SVG. The visualization is built with the D3 v7 library, using d3.pie, d3.arc, d3.scaleOrdinal, and d3.csvParse to fetch and process the remote CSV data.
