This pie chart shows the percentage distribution of programming language usage among developers. The visualization uses D3 v5 (d3.pie, d3.arc, d3.scaleOrdinal) to compute and render the pie slices as SVG paths, with each slice labeled by its percentage. Data is loaded asynchronously from a raw GitHub CSV file using d3.csv. A legend on the right maps each language to its corresponding pie slice color, using various named CSS colors. Both the pie segments and legend are generated procedurally from the same dataset.
