Jonathan Frakes sits at 0.93 — the strongest pull in Brent Spiner's top 10 — and the second peak belongs to Wil Wheaton at 0.91, with Michael Dorn close behind at 0.89. These two clusters define the two-peak shape: a tight band of fellow cast members at the top, then a second grouping of genre-adjacent figures further down.

Seven of the top 10 neighbors share Spiner's own subcategory — Actors — making this largely a same-kind audience map. The exceptions are telling: Weird Al Yankovic (Musicians and Bands, 0.84), Star Trek (Movie Franchises, 0.82), and Alton Brown (TV Personalities, 0.79). Yankovic's presence at position five, sitting between the cast-member cluster and the franchise brand, is the clearest cross-kind signal in the set. Jeri Ryan (0.85) and Alan Tudyk (0.81) round out the actor cluster, while Patrick Stewart (0.78) and Nathan Fillion (0.78) anchor the lower end — both actors, but from slightly different genre orbits than the top three.

The overall shape is a concentrated fandom audience: one tight cluster of franchise co-stars, a second cluster of genre-adjacent actors and one musician, and a franchise brand tying them together — with almost no drift outside the actor and sci-fi/genre space in the top 10.
