this looks excellent. few asks for you -

• new to streamlit, seems like a hosted service. how is deployment handled? Can moest have its "official" deployment ?
• can you add input fields so that the parameters can be modified from UI itself ?

Thank you. I'm working on other features such as filtering and maps as of now. About deployment:

• You can deploy it on streamlit cloud itself. OR
• You can deploy it on private server as well.
• For running locally, you can just install the requirements and run streamlit run app.py from the terminal

• can you add input fields so that the parameters can be modified from UI itself ?

I was thinking of doing something like this. I could work on this on my free time. Seems like cool thing to work on

Thank you @dhirajraut1 and @aashu-kattel. Merging this one as the demo and interface is more compelling.

streamlit seems to be a better alternative to google collab (#14) see if you can help out with map enhancements (#9)
