Does Numbers on the iPad pro allow you to sketch with the Apple Pencil? Using Apple Numbers a lot on my iPad iOS 9.2.1

Due to the limited availability, I haven't seen anyone sporting an Apple Pencil with an iPad Pro. Stores in my area have the iPad Pro but no Pencil.

Does Numbers on the iPad pro allow you to sketch with the Apple Pencil? What happens when you sketch on the Numbers canvas? Can you freehand a simple sketch?
Short answer No

The background that tables, graphs, images etc. rest above is just a workspace. 

It's not a canvas. (Just to be complete I did try it with my Pencil in my iPad Pro)
