I’m a new user of streamlit and I think it’s awesome, so first of all, I need to say thanks to the developers and the comunity.
Currently im working in a project of visualizing air polution in a choropleth map, and I started using Altair.
I followed this tutorial (https://medium.com/dataexplorations/creating-choropleth-maps-in-altair-eeb7085779a1) for creating a Choroplet map from a geopandas file, and it works fine when I work from jupyterlab, but when I try to integrate in streamlit, the map doesn’t show the colors, and I only got a gray map.
I’m creating the map using the function gen_map (which is defined in the medium tutorial), and using the function st.altair_chart() to plot it.
Does anyone know how to solve it?
