After the two maps, I decided to just play with dots and lines. After a bit of that, I just stopped. I looked at it since and decided not to go further.
For this map drawing I drew the colors first. Then I added lines and dots second. Finally I drew larger dots once I determined the most connections across a color.
So I got bored and fell back on a compulsion for fictitious mapping again. This time I began with lines and dots. Afterwards I added color based on the shapes created by the lines and dots.
