The hand is viewed from a slightly elevated angle, showing the knuckles and the grip on the marker. The fingers are gently curled, and the thumb is visible. The marker tip is just touching the page, forming the beginning of a mathematical expression. The background is a plain white page. The style should be detailed and realistic, emphasizing the texture of the skin and the interaction with the writing tool.","has_visuals":1,"visual_count":1,"visuals":[{"id":16,"page_number":16,"visual_type":"Illustration","caption":"None","prompt":"A grayscale, realistic illustration of a human hand holding a black marker, positioned as if writing on a white page.
