The page you need to open to get a safari crashed

0. It seems that since iOS v15 the option "GPU Process: Canvas Rendering" is enabled by default, but if it is disabled, go to setting and enable it explicitly
1. Open the page https://bl.ocks.org/timocov/raw/648966ce5c57492e82864b4d78a7c1cb/?raw=true (the same page in attachments or here https://gist.github.com/timocov/648966ce5c57492e82864b4d78a7c1cb)
2. Wait some time until the page is crashed

If you disable this page, everything will be good and no page crash.

On iOS 15.1 the issue still persist.
