Bokeh chart doesn't show

Following the example in the docs my app runs but no chart is displayed. There are no errors, but I do see a brief flash of blue on the screen which I think usually occurs before a plot is shown. I am confident the chart is created since I can save and download the html file if I try. I’ve tried chrome and safari. Any advice?


@robmarkcole am having same problem, have you been able to resolve

I have the same problem with an altair bar chart. A previous version of the same app worked perfectly but now that I increased the date it just doesn’t show.
