This interactive 7-way Venn diagram visualizes 127 possible set intersections among sets A through G, with each region’s size proportional to the intersection’s magnitude. Hovering any region highlights it and displays a tooltip listing the intersecting sets and their size. The visualization uses venn.js with D3.js v7, applying colors per set and styling circle labels with contrast-aware text color. Computed intersections, including two-, three-, four-, five-, six-, and seven-way combinations, are predefined in a data array passed to `venn.VennDiagram()` for layout and rendering.
