<think>Target shape: yellow rectangle at (0, 0)
Distance from target shape to orange square at (1, 1): 2
Distance from target shape to gray rectangle at (4, 1): 5
Distance from target shape to purple right_triangle at (3, 2): 5
Distance from target shape to brown rectangle at (1, 2): 3
Distance from target shape to red rectangle at (0, 3): 3
Closest shape is the orange square at (1, 1) with distance 2</think>
