Drawing better-looking Bézier curves

There are some interactive widgets, but if you can forgo those, here is a screenshot of that page: https://screenshots.firefox.com/CoUJDgqyX5NtfC6v/beta.observ...

I thought this article would explain how to do curvature based tessellation of higher order curves. That way you can draw better looking curves when approximating them with (a limited number) of (straight) segments.

You're using 'tessellation' in a weird way. Anyway, if you want to calculate optimal knot positions to approximate a curve using some fixed number of straight (or polynomial) spline segments, there are a bunch of papers about that, or I think there's a relevant chapter in De Boor's book.

Spiro Curves are a nice alternative: http://www.levien.com/spiro/

Raph Levien's thesis is great, http://www.levien.com/phd/phd.html

Are the sliders working for you?

I just realised this is the guy behind xi-editor and the Inconsolata font. My mind is blown. https://en.wikipedia.org/wiki/Raph_Levien
