Traditionally, cartography is the study and practice of making maps -- but I'd argue that maps can take many forms beyond the traditional geographic. Mind maps, for instance, to show the flow and connection of ideas.
Really, that is very interesting.Tell me more
Have you ever seen a mind map? It's a diagram to visually organize information.
I heard of these type of maps.What are they usefull for?
It's a great way to *see* and to visualize information. There's a single concept at the center of the map, then other ideas that branch out from that. 
It looks like you know a lot about the subject, tell me more,please.
Well, I do something called "graphic recording" where I work with organizations to create large-scale, visual notes created via live capture while the event's going on. A mind map is a *form* of visual notetaking, but more highly structured. It's just a great way to visually capture and reflect on information.
This information is priceless.thanks for sharing.
If you're interested, there are lots of books out there to learn more. It's definitely a more fun way to interact with and absorb information. Visuals and diagrams always help in organizing information!
