Rules of 'Black And White'

Each square in the grid will contain either a black circle or a white circle. Fill in the grid with the correct set of circles such that there is a single connected group of white circles and a single connected group of black circles. Cells are connected horizontally and vertically. Nowhere in the grid can there be a 2x2 group of squares all containing the same colour circles.
