@humanetech Hmm ... not sure what to do about that. If the SVG shows fine when viewed locally, and fine on the server to which it's uploaded, then it must be on the system you're using to display it, and I don't have any control over that.
I'd be happy to receive suggestions for action to take.
@ColinTheMathmo I was uploading from saved SVG because the image is only temporarily stored on your system.
I have reverted the post to its first revision that links to SVG on your server, and that works fine.
You might consider storing generated images on e.g. a PixelFed instance, or maybe on archive.org or somewhere else that is suited for long-term storage.
