@shammamah It's possible @CanerIrfanoglu might be able to help resolve this one once he's finished tackling updates to the brain surface viewer application.

@shammamah , I looked into this one and I think we can really speed things up by replacing plotly.py graph_objects with dicts since most of the app's cpu cycles were spent validating the updated graphs. I don't really know how this repo flows but I made a PR that will merge into the dash-wind-streaming branch in #332 that does that.
