How to make a mind map in free form?

Question

Project management

Hello. Please tell me, is there a service or program that allows you to create something like a mind map but without being tied to a form? That is, what would not be tree-like. What would be the opportunity to connect one point with several other points, in general, as in films when a detective on a board connects crime scenes

Answer 1

Try graphviz . It allows you to automatically build graphs from the code that describes the relationships between elements.

Answer 2

Maybe: coggle.it

Answer 3

I recommend mindmeister.net , it's all there, you can move, disconnect, reconnect elements in free form.
