Niall Horan and Liam Payne form a clear two-peak structure at the top of Louis Tomlinson's similarity graph — scoring 0.99 and 0.97 respectively, well above the rest of the field — before the curve drops into a much wider, more varied cluster. These two neighbors are the structural anchors; everything else is secondary.
The shape is two-peak, meaning the audience bridges two distinct neighborhoods. The first is fellow musicians: beyond Niall and Liam, Michael Clifford (0.96), Calum Hood (0.94), Austin Mahone (0.94), and Harry Styles (0.91) fill out a band-and-solo-artist cluster that accounts for six of the top ten neighbors by subcategory. The second neighborhood is more eclectic: Cameron Dallas (0.95) and Connor Franta (0.93) are Lifestyle subcategory, Markiplier (0.94) is a Tech Personality, and Steve Austin (0.93) is an Athlete — a subcategory that, looking further into the broader neighbor set, expands into a substantial WWE-adjacent cluster. That cross-kind reach into gaming personalities, lifestyle creators, and combat sports figures is the structural surprise: the audience that follows a musician in this mold also maps closely onto audiences that follow very different kinds of entertainers.
The two-peak pattern here reflects an audience that is simultaneously tightly bound to a specific pop-music peer group and broadly distributed across mid-2010s internet and entertainment culture.
