"Idea Graphics" is what I used to like calling "Mind Maps". For me it's a clearer description and includes many other techniques for creative thinking.
After all the procedure involves ideas not "minds". It's a visual representation (a graphic) that allows for clarity of ideas and creativity. It's not always a "map".
It does not have to be a set method or procedure like using a certain number of colors or using a computer program to set things up for you.
An even better name is "Concept Mapping". But I'll stick with "Mind Map" because that's what most people call it.
