text: Title: Render Plotly graphs in Sphinx documentation
  Body: Currently the Sphinx docs (https://ridgeplot.readthedocs.io/) do not render live plotly graphs. Instead, they contain static screenshots for all available examples.
  
  We could make use of [Sphinx-Gallery](https://github.com/sphinx-gallery/sphinx-gallery) to help us use real Plotly graphs. See [**this example**](https://sphinx-gallery.github.io/stable/auto_examples/plot_9_plotly.html) from their docs.
