The only downside I found of using go.Scattergl is that the browser may have a limit of GL contexts that it can display at once. See this issue. You may get it to work on Chrome by launching the app from the command line with the --max-active-webgl-contexts argument to specify explicitly the maximum number of WebGL contexts, but it’s definitely less convenient. But if you stick to 8 graphs or less on the same page, you should not run into that issue.
