Can I easily create a surface like this using Grasshopper? I’m still inexperienced in organizing data. I don’t need all the scripts, just recommend some grasshopper components would be fine.

And yet scripts are what you got. Doubtful that general purpose magic exists for this, one must think 
More interesting? Generalized for multiple polylines. (yet another vase)
Thank you so much! I have learned a lot!
I’m so grateful! You’ve taught me so much!
This takes the idea one step further, using curve divisions to set height (Z) and radius of the polygons:
Most excellent Joseph - thanks for sharing that method. I’ll add some tweaks to make 3D printable designs, but that will be easy given your base to work from.
PS: I still haven’t been able to figure out how your final Extrude does what it does. 
Extrude To A Point (all segments to their opposite points)
P.S. Added thickness and a bottom:
Yes, I’ve used Extrude to Point many times - It just never occurred to me to extrude a line segment. So Thanks for pointing that out.
