Google Fusion Tables to be
shut down on December 3, 2019
Google Fusion Tables was launched almost nine years ago (snip)
For a long time, it was one of the few free tools for easily
visualizing large datasets, especially on a map. Since then, Google
has developed several alternatives (snip).
In order to continue focusing our efforts in these areas, we will be
retiring Fusion Tables. We plan to turn down Fusion Tables and the
Fusion Tables API on December 3, 2019. Embedded Fusion Tables
visualizations — maps, charts, tables and cards — will also stop
working that day. Maps using the Fusion Tables Layer in the Maps
JavaScript API v3.37 will start to see errors in August 2019.
