I prepared a mind map about Scrum with the help of several references few months ago. It contained main Scrum topics with few details to let us understand Scrum. You can get it from the link below.
I had been thinking about improving the content of the mind map by adding details from the Scrum Guide prepared by Ken Schwaber and Jeff Sutherland. After reading the Scrum Guide again, I prepared an extended version of the mind map by adding more details and extra concepts that are not stated in the guide. I marked extra concepts that are not stated in Scrum Guide in red in order not to cause any confusion. You can find the mind map below.

I hope the map can help you as much as it helps to me.
