I am having trouble developing a Sequential Function Chart (SFC) in LabVIEW. I found some videos online showing successful implementations (screenshots attached), but without the source code.

I don't know how they are achieved(it is possible they utilized the 2D Picture control). Has anyone worked on similar projects and can offer some help?

Similar to Siemens PCS7 SFC, I need to arrange specific modules in a certain order—either sequentially from top to bottom or in parallel.

I have already figured out the execution logic. My main challenge is how to implement the graphical editing functionality.
