Material Dashboard with Bokeh embedded in Flask

Features

The package provides a starter pack with an interactive Bokeh plot embedded in a Material Design Dashboard, which can send parameters from a flask form to Bokeh.

Note

Please keep in mind that this is only a lightweight example of how Flask can affect the rendering of the bokeh plot. The change in scale is out of scope.

Pull requests

If you have differences in your preferred setup, I encourage you to fork this to create your own version. I also accept pull requests on this, if they are small, atomic, and if they make my own packaging experience better.
