Visualization of the output.json

[LittleFlyFish]

Hi Roy,

I already get the trained data output.json and detection_result.json & tracking_result.json for the Nuscence dataset. I am not sure how to visualization these results or visualization the dataset? Could you provide some examples in the readme files for data visualization? That would be greatly appreciated! For example. how to use the plot_tracking.py in the command or plot_utils.py?

Thank you very much!
