On geospatial data...

Data Storage: If your dataset is small, a GeoJSON or shapefile might suffice. For large-scale datasets, consider using GeoParquet or storing data in cloud platforms like AWS S3.
Processing and Analysis: You might use Geopandas for local data, PostGIS for large-scale vector data, or Apache Sedona for distributed spatial computations.
Visualization: Tools like QGIS, Kepler.gl, or even web-based dashboards can help you convey your insights. Plus the increasing number of web GIS tools
