Verify that viewer has basic capability to handle the 'line' shape element and its attributes. Six diagonal lines should be displayed at the top, with color varying and width increasing from left to right. The trough-like figure in the middle, drawn with five 'line' elements, is repeated in the lower-left, with wide blue lines, and in the lower-right with wide multi-color lines.

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 black), stroke (simple colors and wide lines), font-family ("Helvetica"), and font-size properties within the 'style' attribute.
