This pie chart shows the percentage distribution of the most-used social media platforms, with each slice labeled by its percentage value and a color-coded legend listing platform names. The visualization is built with D3 v5, using d3.pie and d3.arc to generate the segments, d3.scaleOrdinal to assign categorical colors, and d3.format to display numeric labels. Data is loaded asynchronously from a CSV file via d3.csv, and the SVG rendering positions the chart and legend within a fixed 960x500 viewport.
