black and white (logic puzzle)

In the standard form of this puzzle type, a grid is given with black circles in some squares and white circles in others, but mostly blank. To solve it you must fill in either a white circle or a black circle in each box so that all the white circles form a single orthogonally connected group, and the black circles also form such a group.
