"Save graph" on relay-search gives me what looks like it's trying to be an svg but it only kind of is?

On my relay's relay-search page, there are some graphs at the bottom. They each have a 'Save Graph' link I can click. When I do, I download something of the uri "data:data/xml" and the first few lines of it make it look like it's trying to be an svg (<svg version="1.1"...). But Firefox loads the resulting file as a text file, the file command's best guess is "ASCII text, with very long lines", etc. It looks like xzgv does know how to treat it as an svg, but it renders it as this weird-looking thing with no x axis or y axis, etc.

Is there a better way we can offer to save the graph?

My workaround so far has been to use Firefox's 'take a screenshot' feature and basically just make my own picture of the graph.
