+## Graphic Unit Interface
+**PyGeM** is now provided with a very basic Graphic Unit Interface (GUI) that, in Ubuntu environment, looks like the one depicted below. This feature can be easily used even by the pythonists beginners with not much effort.

 ## Dependencies and installation
 **PyGeM** requires `numpy`, `numpy-stl`, `scipy` and `matplotlib`. They can be easily installed via `pip`. 
 Moreover **PyGeM** depends on `OCC` >= 0.16 and `vtk`. These requirements cannot be satisfied through `pip`.
