I want you to make a class that represents a circle.

The circle should have a radius, a diameter, and an area. It should also have a nice string representation.

For example:

>>> c = Circle(5)
>>> c
>>> c.radius
>>> c.diameter
>>> c.area

Additionally the radius should default to 1 if no radius is specified when you create your circle:

>>> c = Circle()
>>> c.radius
>>> c.diameter
