At 0.99, Optometry sits in a category of its own — the gap between it and the second-nearest neighbor, DSW (Designer Shoe Warehouse) at 0.86, is larger than the spread across the remaining eight combined. That structural spike is the defining feature of Pearle Vision's similarity graph.
Below that dominant neighbor, the top 10 scatter across a wide range of subcategories with no second cluster forming. The Men's Wearhouse (0.85, Mens Apparel) and LOFT (0.84, Womens Apparel) represent apparel; Pet Care & Services (0.85) and Dogtopia (0.83) are the two Pet Care and Services entries; La-Z-Boy (0.84, Furniture Stores), Portillo's Restaurants (0.84, Casual Dining), Music (0.83, Music retail), and Barnes and Noble (0.83, Bookstores) round out the set. None of these share Pearle Vision's own subcategory — Optometry appears exactly once in the top 10, as the dominant spike itself. The nine cross-kind neighbors span five different categories and eight different subcategories, with no single one appearing more than twice.
That combination — one near-perfect same-kind match and a broadly dispersed cross-kind remainder — indicates an audience whose shape is highly specific at the top but not anchored to any single retail or service cluster below it.
