The top 10 neighbors for Diane Keaton form a tight, mixed cluster — actors, musicians, a TV personality, a reality TV figure, and a magazine — with scores spanning only 0.88 to 0.83, a narrow band that defines the flat shape.

Bette Midler leads at 0.88, followed closely by Jane Fonda (0.86) and Stormy Daniels (0.86). Rosie O'Donnell (0.86) and Mia Farrow (0.85) round out the top five. Of the ten neighbors, five carry the Actors subcategory — Bette Midler, Jane Fonda, Mia Farrow, Gwyneth Paltrow (0.85), and Julianne Moore (0.82) — making actors the dominant type. The remaining five span Musicians and Bands (Cher at 0.84, Barbra Streisand at 0.84), TV Personalities (Rosie O'Donnell), Reality TV Stars (Stormy Daniels), Comedians (Kathy Griffin at 0.83), and Magazines (Rolling Stone at 0.84). The one non-celebrity neighbor — Rolling Stone — sits comfortably mid-cluster, suggesting the audience's shape extends into print media without any single entity pulling away from the pack.

The flat distribution across this mix points to an audience with broad, evenly distributed overlap across a specific generation of female-led celebrity and entertainment culture.
