You're right, it takes an artistic license with the information and fails any strict requirement of necessity. There are 320k of movers that year though and a transient particle was the only option I saw to display all of them. Screens just don't have the resolution to overlay that much information. As you point out, aggregation and faceting both solve this, but I really wanted to show all of them. That has more though to do with creating an experience of having seen a certain phenomenon than creating something actionable and clear. It's self indulgant, but I like that. And I agree: static representations with aggregate data would be interesting.
