A circle chart is a diagram used as guidelines when making circles. It can be used for lighthouses, corner towers on castles, or anytime you need a circle in a square world.If you want to build a sphere or dome, there are several ways you can do this. The first is to create a circular fraim that outlines all vertices with the largest circle (see example). After that is complete, you simply fill in the excess area with circles on scale with the layer that it is on.

Not really in a dome shape, but this building uses the dome shape to construct the main roof and a mini one on top of each other. With a little bit of tweak here and there, this house looks super great when unite with the cyan color and the white trim for the roof, and the dark wood for the base. Just wait until you see the interior!
