Verify that interpreter/viewer has basic capability to handle the 'circle' shape element and its attributes. Six circles should be displayed in two rows with three different sizes in each row, thus exercising the cx, cy, and r attributes. Filling, stroking, and filling-plus-stroking are tested, as labelled for each circle, with simple variations of color and stroke width.

The rendered picture should match the reference image, except for possible variations in the labelling text (per CSS2 rules).

This test uses 'text' and 'path' elements, as well as fill (solid simple colors), stroke (simple colors and wide lines), font-family ("Helvetica"), and font-size properties within the 'style' attribute.
