-  This in an HTML Import-able file that contains the definition
-  of the following elements:
-
-    <load-charts-api>
-
-  It makes sure the Google Visualization api
-  (https://developers.google.com/chart/interactive/docs/) is loaded.  This api
-  is also loaded by the google-chart element, but we need to make sure it is

-
-  Usage:
-
-    <load-charts-api></load-charts-api>
-
-  Properties:
-    loaded: Boolean, true if the charts api has been loaded.
-
-  Methods:
-    None.
-
-  Events:
-    None.
