Description

It would be really nice to be able to take two figures created with Plotly Express (or really anything else) and "glue them together" side by side or one above the other, something like fig3 = compose([fig1, fig2, fig3], orientation="h") or something even more powerful.

I love how ggplot patchwork https://github.com/thomasp85/patchwork and Altair https://altair-viz.github.io/user_guide/compound_charts.html do this!
