I know of no studies like this.  it is used as a shape-preserving curve for 3d modeling (NURBS), roller coaster design (mostly), railways, building and road design, etc.
this is what I learned from a google search on "akima spline graphic design".

honestly, I don't think it's been done in a paint app before.  Everybody has been sticking to bezier and straight lines so far.
The code for akima is about 140 lines long excluding the sort routine (I am not sure, but I think it needs a sort routine to sort the points along the X axis).

I would be satisfied whether I got a clothoid or akima or some other interpolating cubic spline or method, as long as the curve follows along the points.
