How do you draw a circle without an error? In my items array in I have this item:

	type: 'circle',
	fill: '#FFFFFF',
	stroke: '#000000',
	lineWidth: 2,
	cx: 33.132,
	cy: 54.880,
	radius: 0.437
It draws it but the image is larger and I get this error that I cannot trace to fix:

Warning: Problem parsing viewBox="NaN NaN NaN NaN"
I understand what NaN means but not too sure how to fix it either.
