How can I get the type of map like frankieonpcin1080p?

Look, I am not sure if many people know who he is or anything but he makes videos and he puts a lot of time into his videos. I do too and I make the same type of videos and I am not trying to copy the guy but I need an overlay like this
( but I am trying to make it original and can’t seem to come up with any ideas.

First and foremost how do I create this map effect. I have after effects and particular for those particles. I know just need to know how. Can anyone help me recreate this and give me ideas on how to put a spin on it to make it original?
