Please find my final CMAP attached below.
I took everybody’s suggestions into consideration when developing this final iteration.
I made the difficult choice to keep the bubbles the same colour. When I started to change colour, it became increasingly difficult to assign only ONE colour to each topic, since most of the bubbles fit into many categories. So, I stuck with one colour.
I also intentionally shaped my CMAP to look like the neural network in the brain, which is why the outer shape is round-ish.
Enjoy!
