I'm not familiar with jQuery, but I assume its ajax library has ways to inform the user of error. Anyway, you can also use the query<http://code.google.com/apis/visualization/documentation/queries.html>mechanism that's built into the Google Visualization API, if you know the server provides the data according to the wire protocol specification<http://code.google.com/apis/visualization/documentation/dev/implementing_data_source.html> (one way to achieve that is to use the data source library<http://code.google.com/apis/visualization/documentation/dev/dsl_about.html>). I hope this helps in some way. If not, please be more specific in your question.
