Bezier Curve

Quadratic bézier curve
Inspired from this video: https://youtu.be/aVwxzDHniEw

Drag the points to change the curve.

Bézier curves might still be one of my favorite things in maths. To my surprise there aren't many projects of that kind in snap.
Also look at this cool project I found when I searched for bezier https://snap.berkeley.edu/project?user=franczyk.alex&project=bezier

Sorry for the poor description of some of the variables and block names, hope it's not too messy though :)
