draw a grid with a polyline e.g. If you don't need this grid in your DOM than paint the grid in a overlay from canvas.

Be aware though, that if you editor runs in a secure environment, then the above call will cause a security exception be thrown (in our case it translates to "unknown ecmascript element" or smth like that), so you'll need then to sign your application as well. Additionally, your svg document manipulation should be done on an update/event thread (to prevent synchronization issues), we do it with SwingUtilities.invokeLater, perhaps, there's a better way to do it in Batik ? By the way, right now we'll need a grid (where a grid cell vertical/horizontal size can be dynamically updated by a user) drawn in SVG as well. With a native Java drawing, we use a 2x2 black rect to draw a grid point, with a 1280/1024 view area it takes 64 * 51 rects with a grid cell x&y equals to 20. How do you draw the grid in SVG ?
