The map should not be shared anywhere online. The latitude and longitude columns can be found in the building table of the dhhl project.
Try to see if the map allows for customization of the circles that mark the location of the houses. For example, try to use the readings table + a measure of total appliance cost to resize the circles on the map.
As such, the map should show which house consumes the most in an appliance. See if you can specify rather than total cost only one kind of appliance or try to think of other variables that would be of interest to resize on the map.
See if you observe any patterns when resizing the circles on the map (e.g. neighbour houses always having similar costs).
