Without PDF output it's a chore to share visualizations over email, chat, etc. The uncharted aspect of data visualization is reporting and sharing IMHO.
You can also publish this to the web (https://datapane.com/leo/reports/stock_report_5d2925b9/), embed it into social media (https://medium.com/@leo_26134/embedding-with-datapane-366e60...), or deploy your Jupyter Notebook or Python script so that other people can run them with parameters to generate reports dynamically.
It's still pretty new, so if there's anything you'd like to see, give me a shout at leo [at] datapane.com.
