Add Panel App

I would recommend

• Sorting data app frameworks alphabetically or similarly to not favor something systematically
• Adding a gif such that people can see that app in action. The gif should be recorded on the same hardware.
• Run autoformatting (isort, black) on all code to not favor apps with poorly formatted code.
• Renaming the repo to data-app-comparison or similar. There are +20 other frameworks that could be included.

Consider describing the features that apps do support/ do not support. For example if it was a real Panel app I made I would add cross selections to the plots. Such that when you select a region in the scatter plot the lower one is automatically updated based on the selection. That is something the HoloViz ecosystem does really well while its much harder with Streamlit.

There is also another version of the app. One that is faster, has many more features and using another api that would make the app components much more reusable, testable, maintainable etc. when the app is growing or you have 10s, 100s or 1000s of apps to maintain. I could add it as panel-app-ext.py if there is an interest?
