I have learned how to draw a heart with mathmatical equation, in fact there are so many “curves” you can draw with equation. Amazing, right?!? You can find all sorts of different curves on Wolfram Mathworld site. I’m really curious how did people find equation itself for some of shapes?

Tableau has chart type called “Packed Bubble Chart”, while I haven’t really utilized packed bubble chart much, I always thought they are fun and beautiful. I wanted to try creating same chart using R, and I came across package called packcircles.

I have been playing with package called imager, documentation on this package was extremely helpful! I have read through “getting started” as well as few other tutorial & examples.
