Sorry, I should have said to open it in a browser (Chrome/Firefox); the SVG contains some (entirely embedded) JavaScript to provide interactivity (click to zoom, Ctrl-F to search). I think it used to work in ImageMagick (without JavaScript interactivity), but I haven't tried in a long time. I'll have to check it again.
