plotly.offline.iplot gives a large blank field as its output in Jupyter Notebook/Lab

Question

I am trying to create a Sankey chart in a Jupyter notebook, basing my code on the first example shown here.

I ended up with this, which I can run without getting any

Answer 1

When using Google Colab, include the snippet -

import plotly.io as pio
pio.renderers.default = 'colab'

Or use the overall import statements as -

import plotly.offline as py
py.init_notebook_mode(connected=True)
import plotly.graph_objs as go
import plotly.io as pio
pio.renderers.default = 'colab'
from plotly.offline import init_notebook_mode, iplot

This will set the rendering to Colab style and the plots will be displayed.

Hope this helps.
