AI Drawing Prompt Reference

Draw a plane graph with multiple line segments and intersection points. Start by drawing several line segments and finding their intersections. Then, continue to draw new line segments based on the positions of these intersection points, and find more intersections. Repeat this process until all key points are connected. The final graph should illustrate geometric constructions and limit phenomena, suitable for students learning geometry and coordinate geometry.
