2d vector tools?

Hello. I have been looking into what kind of tools Unity could provide me with a small project. I can see that there's a lot out there regarding 2d sprite based games. But what would be the best way to go about quickly getting a simple 2d vector based game up to speed in Unity? Say, if I was after a visual style similar to Reassembly, which is just crisp lines and solid filled areas, more or less:

I have in the past used graphics libs, where I've just had my shapes stored as series of coordinate pairs, rotated those according to state and drawn them using a simple line drawing function. Is this approach easily available in Unity, and especially, is there anything better? Either in the core product or in an extension. Just looking for someone to point me in the right direction on what approach would be best to use, thanks.
