The MultiGeometry layer is the default Google Fusion Table layer. It can be used to represent points, lines and polygons.
Clicking on any of the features on the map will show all the data associated with the spatial feature which is all
the data in the Fusion Table's row associated with the geometric feature.
Polygons and lines are taken from KML file uploads and these features are stored in the Fusion table as a row.
Points in a KML layer can be taken from either CSV or KML uploads.
The symbology of the MultiGeometry layers can be altered in the Google Fusion Tables application.
The MultiGeometry symbology settings provides a link in the
Metadata View to
navigate to the Google Fusion Table application.
Once there you can navigate to:
Visualize > Map > Configure Styles
To change how the MultiGeometry layer's points, lines and polygons are displayed.
