Freeplane is a mind map creation and design tool with which we can put all our ideas in order and create complex schemes in a very simple way.
For the creation of our scheme we will have a multitude of possibilities: quick links between concepts, creation of new nodes, insertion of images and icons, different types of view (in the form of a cloud, classic scheme, etc.) and dozens of format possibilities .
Within each of the ideas or tasks that we create in the outline, we can write a longer document in which, thanks to a built-in text editor, write down everything related to that point. In this way, we will achieve an apparently small scheme, loaded with content.
Freeplane is a tool with many possibilities when it comes to creating diagrams, although its unpleasant interface makes it a bit harsh at first.
