Create graph paper with mtpaint

[MochiMoppel]

I don't see the need for an SVG image.
1. A grid image should NOT be scalable. Would be like a band measure made of rubber. Works only if you are careful.
2. You would need an SVG application to use it. Inkscape comes to mind, but inkscape already has an excellent grid tool on board.

You can also create graph paper online and download as pdf. For a dummy like me this is easier
