Dustin Johnson's top 10 nearest neighbors form a tightly bounded golf ecosystem — tour infrastructure, fellow tour players, and golf media — with scores compressed into a narrow band from 0.98 down to 0.97, the hallmark of a flat shape.

PGA Tour leads at 0.98, followed immediately by Golf Channel (0.98) and Rory McIlroy (0.98). Jason Day (0.98) and David Feherty (0.97) round out the five closest neighbors. The subcategory breakdown across all ten is almost entirely Athletes — McIlroy, Day, Phil Mickelson, Jordan Spieth, Jack Nicklaus, and Justin Thomas all carry that label — with two non-athlete entries: Golf Channel (TV Channels) and Feherty (TV Personalities), and one organizational entry, The Masters (Sporting Events). No brands appear in the top 10; the nearest brand neighbor sits outside this set. The pattern is same-kind dominance: six of the ten neighbors share Johnson's own Athletes subcategory, and the remaining four are golf-specific media and events rather than any cross-sport or cross-category presence.

The flat shape and the tight score range together indicate an audience with a sharply defined single-sport identity, where tour players, golf broadcasts, and major championships are all nearly interchangeable in terms of who follows them.
