I have the impression that I do not understand Nancy completely. 
Photoshop is something flat to me, 2D, and if I understand correctly then the excel graph is exported as a 2D image??? And somehow saved as AI??? 

I know something about file formats, but I am missing some important thought here I guess. 

I have been looking in then formula section if Carrara and I failed to find a import function to read from file. Then I have been thinking, maybe I create some formula generator to be imported with copy and paste in Carrara but I am afraid that the script engine is not that powerfull to process a few hundreds of datapoint.   

It is not urgent, I was just wondering how to create visually stunning 3D graphs instead of the excel 3D graphs.  I was thinking about creating a movie of how the sales have morphed or something similar like a blokbuster movie ;-)  Ok creating the graphs by hand is also a way of doing it, but it would be nice if it could somehow be semi-automated. 

Thanks for the feedback
