The main subject is a large, shallow, bowl-like or spherical segment shape, viewed from a slight angle, with its opening facing upwards. Inside this larger shape, a smaller, similar bowl-like shape is nested, also viewed from the same angle. The larger shape has points labeled 'P' at its highest point, 'A' at one edge of its opening, and 'D' at a lower point on its curve. The lines are clean and precise. The diagram is overlaid with faint, cursive handwritten notes in a dark ink, appearing as if someone wrote on the page.","has_visuals":1,"visual_count":1,"visuals":[{"id":31,"page_number":77,"visual_type":"Diagram","caption":"None (The diagram is partially obscured by handwritten notes, making any potential caption illegible or indicating its absence).","prompt":"A simple, black-and-white line drawing of a geometric diagram, typical of a mathematics textbook.
