Upload a CSV file and read it in Bokeh Web app
As far as I know there is no widget native to Bokeh that will allow a file upload.
It would be helpful if you could clarify your current setup a bit more. Are your plots running on a bokeh server or just through a Python script that generates the plots?
Generally though, if you need this to be exposed through a browser you'll probably want something like Flask running a page that lets the user upload a file to a directory which the bokeh script can then read and plot.
I have a Bokeh plotting app, and I need to allow the user to upload a CSV file and modify the plots according to the data in it. 
Is it possible to do this with the available widgets of Bokeh?
Thank you very much.
