The top 10 neighbors for Alicia Keys form a dense, same-kind cluster — eight of the ten are fellow Musicians and Bands, with scores compressed between 0.97 and 0.99. Similarity here measures how closely two entities' audiences resemble each other in composition; the narrow band across all ten positions is the defining structural feature of this flat shape.
Mariah Carey (0.99) and Will.i.am (0.99) sit at the top, separated by less than 0.0001, followed closely by AKON (0.98) and Pharrell Williams (0.98). Nicki Minaj (0.98), Ne-Yo (0.98), Jordin Sparks (0.97), and Ice Cube (0.97) round out the musician bloc. The two departures from that pattern are VH1 (0.98), a TV channel with deep roots in music programming, and Carmelo Anthony (0.97), the lone athlete in the set. No comedians, actors, or non-music media properties appear in the top 10 beyond VH1. The overall spread from first to tenth is just 0.017 — a tight band that signals no single neighbor dominates and no sharp audience boundary separates any of them.
The shape describes an audience that moves coherently across a broad swath of R&B, hip-hop, and pop figures without concentrating on any one of them.
