# Huggingface Streamlit Toy

This is a toy to play around with Huggingface, Leafmap, and Streamlit

I'm looking to implement at least these things:
* Visualize raster data from an S3 bucket
* Let the user (you!) draw polygons and calculate some stats (mean, median, etc.)
* Let user load pre-defined geometries (admin levels? country borders?)
    * Load boundaries based on the center of the map
