Mind maps are diagrams used to organize information visually in hierarchical ways that show relationships among the elements that make up the map. Drawing mind maps have been proven to be highly effective for getting information in and out of the brain especially when combined with logical note-taking that typically details or summarizes the roles of the map’s components along the way.
There are various mind mapping software out there ranging from free to paid to open source options.
