Plotly - notebook / Very slow render with many graphs

📊 Plotly Python
7

Hi all,

I’m working on a big refactor of the plotly.py rendering subsystem in https://github.com/plotly/plotly.py/pull/1474, and one of the new renderers is going to be an iframe renderer that stores each figure as a separate HTML file in a directory next to the notebook and then inserts an iframe in the notebook that references the HTML file.

I would appreciate it if some folks who have notebooks that are bogging down JupyterLab could give this branch a try (installation instructions https://github.com/plotly/plotly.py/pull/1474#issuecomment-476663406) and report back on whether the iframe renderer improves responsiveness. To use the iframe renderer on this branch, don’t call init_notebook_mode(), but do call…

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

once at the top of the notebook before displaying figure with iplot.

One limitation of the iframe renderer to be aware of is that doesn’t support responsive resizing. As of 3.8.1 the iframe renderer supports resizing.

Thanks,
-Jon
