Hi, It sounds like you're reading Gabriel Svennerberg's book. I can't speak to using the output from the Styled Map Wizard in the way that you describe, but as far as reading data from a JSON and using it to populate a Google Map (API v3) an example is located here:
http://gis.zgroks.com/NYwithCountyLabels.html // This example reads from a JSON file and creates moveable (Infobox) labels for the counties of New York State. The take away is how to read the JSON file.It shows one way to loop through a JSON file and grab the properties from the file to create markers or do whatever. In the example above, the data is stored in the file: "http:// gis.zgroks.com/nyCountyLabeldata.json". The JSON file consists of the array "centroid[]" and starts and ends like what's below: var centroid = [ {"countyFIPS": "001" ,"countyName": "Albany ","population": 304204 ,"lat": 42.678976,"lng":-73.813040 }, ... Rest of the data goes here ... {"countyFIPS": "123" ,"countyName": "Yates ","population": 25348 ,"lat": 42.633657,"lng":-77.078037 } ]; This data file is pulled into the main script like this: <script type="text/javascript" src="nyCountyLabeldata.json"></ script> // right after you pull in the Google Maps Api v3 ... This gives your script access to the JSON object as a "global variable". To loop through the JSON object, the script says this: for(var i=0; i<centroid.length; i++){ var obj = centroid[i]; var latLng = new google.maps.LatLng(obj.lat,obj.lng); var pops= obj.population; var labelText2 = obj.countyName + " County "; var marker = new google.maps.Marker({ position: latLng, // }); var myOptions = { // code omitted from example; // end myOptions var ibLabel2 = new InfoBox(myOptions); ibLabel2.open(map,marker); } // end of loop that reads the JSON file The loop traverses the centroid[] array. In turn, each element is assigned to 'obj'. Each time through the loop you read whatever you want from the variable obj[i] such as obj.population which is the same as obj[i].population, etc. Before the script leaves the loop, it does whatever it needs to do with the properties that are read from each element of the centeroid[] array. I'm sure there are better, more elegant/unobtrusive ways in which to do this and you could read from an XML file as well; however this does work as a starting point.
