Connect and visualize key points

[caochengchen]

May I ask how to connect the key points to visualize them after I have obtained the key points of the whole body? I know that the data format and color are defined in your code, but I don't know which code is for graphic drawing, can you tell me? After using your pre-training model, the extracted key points can be automatically connected and visualized. I believe the code you provided has a program to realize such a function, but I can't find the specific location of it, please help me
