Live demos show creating interactive web maps with folium (leaflet wrapper), centering and saving maps as HTML and adding markers; building a geopandas geodataframe with a geometry column (CRS EPSG:4326), filtering and choropleth plotting; using shapely for distances and intersects; adding basemap tiles via contextily (including satellite tiles); opening GeoTIFFs with rasterio, extracting contours and masking rasters with a GeoJSON (UTM32 coordinates). Code runs in Jupyter and the examples render and save as described.
