Javascript visual if / else drawer

I'm now working on a project, for which I need to create a "visual condition" maker.

I need to be able to draw a diagram that will create a visual path like this : Statement A choose a) b) c) If a) then... If b) then... If c) then... etc...

But in a visual form, like you know, draw.io or think kind of stuff.

But I have no idea where to look at, if there is already some library I can use, or build on the top of, etc...

Do you have any advices or suggestions ?

Thank you so much for your help & time !
