I'm sure someone will find a use for this: https://spotify.github.io/coordinator/

It's an open-source project by Spotify that takes an SVG file and subsequently lets you finetune the dot placement. You can save the result as (X,Y) coordinates (both CSV as well as JSON), or as a PNG image. I haven't tested this, but the ImportPointFile from http://moi3d.com/forum/index.php?webtag=MOI&msg=5124.2 should be able to import the generated CSV data into MOI.
