software for graphical note taking on note 4?

[merlin7777777]

I'm about to get a note 4.

I want to take notes graphically e.g. a mind map, and I wondered if there is an app which will translate my handwritten text and squiggles jnto a formal diagram i.e. like handwriting recognition but for diagrams?
