This is built with Panel that builds on Bokeh. I think that it can develop into something truly powerful over time.
I am looking forward to getting some experiences from operation. I can see it utilizes my server more heavily than the other applications at https://awesome-panel.org. If any body has an idea on how many simultaneous users I should expect to be able to serve from 1 bokeh server with num-proces=4 running on a low end DEV/ TEST server I would like to know.
Check it out at https://awesome-panel.org/streaming-plots where you can also find the source code.
