To explore the Datasets available to you, click on the ‘Data Layers’ button in the top left of the map view.
This reveals a list of all the Datasets that have been enabled for your geography. The source and date of publication for each Dataset are shown in smaller grey text above the name.
Use the toggles to turn Datasets on and off. Datasets are automatically coloured according to the dataset types they represent (e.g. population data, jobs data, point-of-interest (POI) data, etc.).
Note that only the Datasets with at least one data point in your map view are shown in the Data Layers. If you cannot see a Dataset you expected to find, try zooming out on your map to reveal more Datasets.
