Add example flame graph, to be linked from bitcoin docs.

[eklitzke]

I know this seems weird, but I want to host an example flame graph on bitcoincore.org so it can be linked to from the flame graph docs I'm trying to add in this pull request. There is some discussion in that PR, but to summarize:

• GitHub won't host interactive SVG files (their CDN renders them as a static image)
• I think having a zoomable, interactive SVG file linked to in my docs makes the demo much more compelling
• I'd prefer to host the file on an official Bitcoin site rather than my personal domain, mainly because redirecting people to my personal domain seems weird and looks sketchy

Concept ACK. Not sure how to test this.

SVG files are a bit scary because they contain javascript. I don't see anything obviously evil in c45465c at first glance, but it's thousands of lines...

An animated gif seems safer.

@eklitzke what's the status on this? On the closed upstream PR, you note that you plan to move the documentation to the docs repo, but I assume that doesn't satisfy you problem with GitHub not displaying dynamic SVGs. Do you still want this hosted on BitcoinCore.org?

This basically LGTM. If it's still useful, I'll be happy to pick apart the JS to make sure it doesn't do something awful like mimic our Downloads page and give it a test.

No response in a month; closing. I'm happy to reopen if discussion resumes.
