Nowadays black themed UIs are becoming more mainstream, featuring dark/black backgrounds. Most editors I’m using also render SVG images on a black background. As far as I know, I can’t specify a background color for the SVG images generated by PlantText. As a result the diagram becomes unreadable as it features black text/arrows etc on a black/dark background. I think it would be great that the SVG image would specify a white background, in order to make it readable on dark backgrounds. However for backward compatibility and people that display SVG images on light non-white backgrounds, using a transparant background could be considered as the default.
