Given a `Circle(Point(1,2), 3)`, is it possible to calculate the bounding box of it?

You can get bounding boxes for plot objects via `boundingbox(p)`. GeometryBasics also implements some bounding boxes as `Rect(primitive)`

I don’t understand what `Rect` is doing.

```julia

julia> Rect(Circle(Point((0.,0.)), 1.))
Rect2D{Float64}([-1.0, -1.0], [2.0, 2.0])

```

Oh I didn’t notice you responded. The circle is centered at (0, 0) with radius 1. The Rect contains one corner (-1, -1) and the width (2, 2). There are a bunch of functions like minimum, maximum, widths, origin, etc to get specific things from a `Rect`.
