Test your svg graphics
There are some tools to create SVG. PDF2SVG is one of them. Unfortunately, some results are doubtful. The File:test.svg can be modified by anyone, to test their own svg-graphics. Just to test whether the svg is displayed correctly. Internet-Explorer may be able to render correctly (with a better plugin), but the wikibooks can't. If you suspect a problem with the rendering of your graphic, then upload it the first time here under the name test.svg. It's easier than deleting an upload. The test.svg is only a temporary file.
