Draw a smooth curve through a sequence of points
Here’s a simple algorithm for drawing a smooth curve through any sequence of points. The resulting curve is C 2 , which is as smooth as you can get with cubic Bézier curves.

Approximate a circle with cubic Bézier curves
Bézier curves are often used to generate smooth curves because Bézier curves are computationally inexpensive and produce high-quality results. The circle can be closely approximated using a cubic Bézier curve that is constructed to minimize the radial deviation from a circle.
The typographic scale
The typographic scale has been used for centuries to choose harmonious font sizes. It has been likened to a harmonious musical scale. But there are flaws in those historical values.
