A set-based diagram maps each photographic lens accessory—such as lens caps, UV filters, hoods, and gear rings—into overlapping lettered groups (A through Q), with numeric quantities indicating how many of each item appear per group. Using a force-directed layout, the visualization arranges the groups and their shared members to reveal commonalities and differences across the lens collections. The code relies on `d3.forceSimulation` to compute the positions of group nodes and item nodes, while the bundled data from `sets.js` defines the exact membership and counts for each set.
