visual logic designer?

Is there a tool which allows me to design a Python script/logic visually? I am not talking about designing GUI, but design a flowchart and let the tool automatically create corresponding script file in background. Something like this?

Sure. First result on Google:

pro-rsoft you are THE MAN. I like this program. Although I only read the first page of the site. I need something like this. I will check it out today and report on how well it works with panda3d.
