It’s strange that those sorts of “walls” only denote unhinged when the person is an amateur or civilian. You see stuff like that on a policeman’s wall, or an FBI agent’s, and you’re like “Ooh, so there IS a conspiracy!”
Edit: I actually took a tool that I designed originally to build these sorts of maps and modified it to support Intelligence work I was doing, since the professional tool they had was too expensive, and honestly not flexible enough.
