The output of Plotly Express is a normal Figure object which can be exported to static formats like PDF, SVG etc, or to HTML, or uploaded to Plotly Chart Studio, all using functionality from https://plot.ly/python :)

For example: https://plot.ly/python/static-image-export/ for static export, or to save to an HTML file just use something likeplotly.offline.plot(figure, "file.html")

If you have any questions or concerns with these, feel free to ask on our forums at https://community.plot.ly/ :)
