I do have experience with mind mapping but I was quite frustrated with this particular tool. Everything that I did was "too large to publish" so I ended up paying to publish my map. If I ever use a mapping tool again, I will continue to use "Inspriration" . It's way more user friendly and looks nicer. I really disliked that I couldn't move the "arms" of the map around.
Anyway, this map highlights what I thought were the important topics of chapter four. I also included the page numbers to each of the topics if you're interested!
