Hello! I am trying to visualize a 3D scatter plot and I am just in the debugging mode, I can’t visualize a 3D Graph. A dash window appears with an empty 2D chart. Does anybody have any tips?
Hi @jihyun.noh93 and welcome to the Dash forum 
Many things can cause an empty 2D chart to be displayed. If you post a minimal example, someone will probably be able to help.
See this post for more details.
