Reading Method
Catch the summary first, then trace the chapter structure
Start with the summary — quickly grasp what this chapter is about. Then use the chapter graph to see how the key points connect. Go back to the original text only when you need the detail.
Graph + Summary
Chapter graph and summary on screen together — catch the main points first, then follow the thread down.
Chapter Graph
The graph focuses on the current chapter only — it shows how the key points relate, without compressing the whole book into one unreadable diagram.
