Explore GeoJSON representation of census tract data:

[JPMartinezClaeys]

To do the heat maps on leaflet we need to pass the information as a GeoJSON which specifies the geometry in the geometry field and the data to be passed as values for each census tract on the "properties" field.

Solutions to explore:

• Use GeoJSON Django Serializer that converts an object of a model to a GeoJSON object https://docs.djangoproject.com/en/5.0/ref/contrib/gis/serializers/ easy to do but will require to change Demographic data model to be at the Census Tract level.
• Make a query and convert results to GeoJSON:

1. Applying the serializer directly does not seem to work as passing .values() (equivalent to GROUP BY) to a query set convert it to a ValuesQuerySet. Explore if there is a way around this problem.
2. "Manually" create the GeoJSON from the queryset results and then apply geojson.dumps(). Need to explore how geojson interacts with GEOS Geometry used by Django and could be more error prone (but certainly doable).
