Blender graph editor bezier I know how it works in Autodesk Maya but I prefer Blender more. The problem is that in Graph Editor animations curves are not Bezier curves and it's not handy to use for animation. This way I can't handle the animation curves completely as in Maya. Here is example. https://www.youtube.com/watch?v=RGuHdP_b3sk
Can you add Bezier curves in Graph Editor?
On top of other forms of interpolation, blender does use Bezier curves in the Graph Editor 



The interpolation modes for segments of a curve can be determined by selecting a point in the graph an pressing the T key.



Or on the menu Key->Interpolation Mode:



Moreover the default interpolation mode can be determined in the preferences (CtrlAltU)

Some examples.
