The two strongest pulls in Costco Optical's similarity graph are both Costco properties: Costco Gasoline at 0.95 and Costco at 0.95, forming a clear first peak that sits well above everything else in the top 10. The second peak is a cluster of general retail and grocery neighbors — Sprouts Farmers Market (0.86), Target (0.86), and Costco Pharmacy (0.85) — that rounds out the dominant pattern: this audience is defined primarily by membership-retail and big-box shopping behavior, not by eyewear specifically.

The subcategory breakdown of the top 10 makes the cross-kind character plain. Of the ten nearest neighbors, two are Big Box Retailers, one is a Gas Station, one is a General Grocery Store, one is a Pharmacies and Drugstores, one is a Bakeries Desserts and Confectioneries (Cold Stone Creamery, 0.85), one is Movies and Theaters (Movies & Theaters, 0.84), two are General Apparel (Nordstrom Rack at 0.84, Tommy Hilfiger at 0.83), and one is a Confectionery (See's Candies, 0.83). No other Eyewear entity appears in the top 10 — the center entity's own subcategory is entirely absent from its nearest neighbors.

The shape confirms what the scores show: Costco Optical's audience is structured around the Costco ecosystem and broad suburban retail habits, with the optical category itself playing no visible organizing role among the closest neighbors.
