Jonathan Scott is the overwhelming anchor of Drew Scott's similarity graph, scoring 0.93 — a gap of nearly ten points above the next closest neighbor. That kind of concentration defines a spike structure, where one relationship dominates and the rest trail behind.
The next tier clusters around the Property Brothers franchise and its natural orbit: Property Brothers (0.84), HGTV (0.81), and Outlander (0.80). Two of those four are TV Shows or TV Channels by subcategory, reinforcing a broadcast-television core. Justin Hartley (0.82) and Chrissy Metz (0.78) — both Actors — round out the top 10 alongside fellow TV Personalities Guy Fieri (0.79), Jeff Probst (0.79), and Big Brother HOH (0.78). The lone outlier in the top 10 is Mike Golic Jr (0.78), the only Athlete in the set. Across the ten neighbors, TV Personalities and Actors account for six of the ten subcategories, with TV Shows and TV Channels filling two more — a neighbor set shaped almost entirely by broadcast and cable television audiences.
What the spike reveals is an audience defined first by a single co-identity — Jonathan Scott — and secondarily by the broader world of network and cable TV personalities, with no meaningful pull from outside that ecosystem in the top 10.
