To visually display multiple bounding boxes on an image simultaneously, a programmatic function can be defined to iterate over a collection of bounding boxes and draw each one on a plot's axes. For each bounding box, a rectangle patch is generated using a helper function that converts the box coordinates to the required format for the plotting library. These rectangle patches are then individually added to the image's axes. The function can also accept optional lists of colors and labels, applying a specific color to each boundary and overlaying corresponding text labels to differentiate the boxes.
