I have written a Google Fusion Tables script I\'m happy with (below), but it\'s loading only 500 rows of points in my table, which has over 20,000 rows. This is my first tim
The Gviz API does have a 500 row limit for a given query.
Any table is limited to 100,000 mappable rows, but that's well outside your reported 20,000 rows.
The new Javascript API, currently accepting Trusted Testers, offers JSON format support for any number of rows returned for a query. You can apply for the TT program by requesting membership in this group: https://groups.google.com/group/fusion-tables-api-trusted-testers
