I know that one can get smooth point connections with option smooth to \addplot that takes the previous and the next point into account, but this still connects all the points. How can I draw a ...
Motivation In the answer Highlight a group of nodes in a tikz tree, Jake suggested combining the convex hull approach from padded boundary of convex hull with the hobby path and I was really ...
