Here's what I found in a couple of browsers:
Chrome
93.0.4577.63 - runs everything fine
Edge
93.0.961.44 -
runs everything fine
Firefox 91.0.1 - seems a little bit slower rendering the JSFiddle but otherwise OK
Opera
78.0.4093.184 - seems slower than Firefox at rendering the JSFiddle, slow at rendering the local file, can't show the tooltips on either
IE 11 - can't render the JSFiddle at all, slow rendering the local file, can't show the tooltips
If it helps, I've had users reporting problems with some charts I've created if they are using some extensions in Chrome.
How's your memory usage when running this? Opera uses even more memory than Chrome does when running the chart.
