Hi mamlin, thank you for your answer and the advise. Unfortunately the module does not fit our needs. As I can see so far, it simply provides a GUI to upload an image (which you have to create your own) and create a basic HTML image map on it. Things you can do your own if you have some basic HTML knowledge. The module is neither plotting the chart automatically based on some DB date (as mentioned before instead of plotting you have to create the image your own) nor is it providing a GUI to translate an organizational structure into a database structure (meaning that HR officers can delete and create departments/people/jobs etc., change the organizational structure etc., which is all saved in a DB).

Anyways, thank you for the help. Maybe you or someone else know some other module which realizes the above mentioned.
