Test basic HTML-to-CGM link, from a HTML 'A' tag to a whole CGM file, with no fragments, behaviors, or object targets.

At the start of the test, the right-hand frame should contain some HTML text, with a string "Click here to display WebCGM picture." having hyperlink highlighting. Clicking that hyperlink should cause the contents of a referenced CGM file to appear. The CGM contains a simple picture with a green-filled square on the left and a blue-filled circle on the right, both with thick black borders.

Because there is no (HTML) TARGET behavior on the hyperlink, the CGM picture will replace the HTML text in the right-hand frame. This is the standard HTML 4.0 behavior. You should be able to use the browser "Back" and "Forward" buttons to go back and forth between the HTML view and the WebCGM view in the right-hand frame.

The initial view in the left-hand frame is a PNG reference image of the simple CGM file which should appear in the right-hand frame upon activating the hyperlink.
