Ok, I want you to generate an image for me. It should be a kind of architecture diagram and the format should be 1:5 (1 vertical, 5 horizontal). On top there's a horizontal block stretching the whole way which is named "PLanning agent", below that are two horizontal blocks next to each other that are named "Task 1 agent" and "Task 2 agent" respectively. There are arrows from the planning agent to the start of task 1 agent, and from the end of task 1 agent back to the planning agent. Those same arrows also exist for the Task 2 agent. Please generate the image with a white pen in illustrative style on a transparent background. See more
