This library defines keys for creating shapes that go through given points.

• /tikz/circle through=coordinate(no default)

• When this key is given as an option to a node, the following happens:

• 1. The inner sep and the outer sep are set to zero.

• 2. The shape is set to circle.

• 3. The minimum size is set such that the circle around the center of the node (which is specified using at), goes through coordinate.
