Draw a Circle
To draw a circle on a canvas, use the following methods:
- beginPath() - Begin a path
- arc(x,y,r,start,end) - Define a circle
- stroke() - Stroke it
arc(x,y,r,start,end) - creates an arc (a curve).
To create a circle, set start angle to 0 and end angle to 2 * Math.PI.
The x and y parameters define the coordinates of the center of the circle.
The r parameter defines the radius of the circle.
