ARTWORK: A "Map" of H. P. Lovecraft's Universe

Earlier this year, I made a "map" that linked together the story connections in Stephen King's universe.

I thought it was fun, so I did it again, this time for H. P. Lovecraft

Notes for Lovecraft nurds:

1. The locations, characters, and artifacts here are noted only if they're present in a story with three exceptions (see notes 2 and 4).  If I mapped every single time Lovecraft mentions these elements, this would cease to be visually appealing and become a dark rainbowy sludge.
2. "The Picture in the House" and "The Rats in the Walls" mark the first time their respective elements (Arkham and Nyarlathotep) are mentioned in Lovecraft's work.  I've noted the difference with dotted lines.
3. On that note, I've ignored Lovecraft's story fragment "Azathoth," as there's no indication it connects to his alien-god of the same name.
4. Since "At the Mountains of Madness" is Lovecraft's largest effort to unify many of his recurring threads, I've let mentions in that story "count."  The story's the epicenter of his fictional universe, so this seems only fair.
5. Thanks to RT users Takoma1 and Rock for giving me feedback on earlier versions of this map.
6. And thanks to the late, mostly great, adverb-abusing, sometimes-very-racist H. P. Lovecraft.
