I'm putting together an online course to help urban planners with our industry certification exam, and I was struggling with how to organize some of the content. So I made this mind map to help me get a better hold on how I can present a section of content in a clear way.
I started out drawing the mind map by hand, but I realized pretty quickly that I wanted to move things around, combine concepts, break up concepts, etc. So I moved to a website called Miro. Basic functionality in Miro is free, and I already use it for planning other projects visually.
