I am looking for ROS node to visualize ClassificationResult on rviz.
Here is a code that I found in 72b2 desktop (https://gist.github.com/k-okada/7845471a8f6c3140e69cfe77ac6095b5), but I suppose someone already write a similar script and commited on their branch. If you remember that, please let me know.

I know the node to visualize ClassificationResult with jsk_recognition_msgs/RectArray (2D bounding box).
https://jsk-docs.readthedocs.io/projects/jsk_recognition/en/latest/jsk_perception/nodes/draw_rects.html

But I don't know a visualization node to show ClassificationResult with jsk_recognition_msgs/BoundingBoxArray (3D bounding box).
