Hi
I am using google visualization API to visualize data retrieved in
JSON format from a remote data endpoint .
I use the following code to query the endpoint and retrieve data in
Data Table format
var query = new google.visualization.Query('http://data-gov.tw.rpi.edu/
sparql?query-option=text&query=PREFIX++d%3A+%3Chttp%3A%2F%2Fdata-
gov.tw.rpi.edu%2Fvocab%2Fp%2F10040%2F%3E%0D%0ASELECT++%3Fstate+
%3Furban_home_broadband++%3Frural_home_broadband+%0D%0AWHERE+{+%0D%0A+
{%0D%0A++++++++++%3Fs+d%3Astate+%3Fstate+.%0D%0A++++++++++%3Fs+d
%3Aurban_internet_use_in_the_home_broadband_no+%3Furban_home_broadband

+}%0D%0A}+%0D%0AORDER+BY+%3Fstate&service-uri=http%3A%2F%2Fdata-
gov.tw.rpi.edu%2Fsparql&output=gvds&callback=&tqx=&tp=');
// Send the query with a callback function.
query.send(handleQueryResponse);
function handleQueryResponse(response) {
if (response.isError()) {
alert('Error in query: ' + response.getMessage() + ' ' +
response.getDetailedMessage());
return;
}
var data = response.getDataTable();}
Now i am not sure how to use chart wrapper to wrap the above query.My
dataSource requires me to specify other parameters along with the
query.
