Hi ADITYA KUMAR‌, the data will be

photoInfo.data = arrayUtils.map(resp, function(p) {
              var latlng = new  Point(parseFloat(p.lng), parseFloat(p.lat), wgs);
              var webMercator = webMercatorUtils.geographicToWebMercator(latlng);
              var attributes = {
                "Caption": p.caption,
                "Name": p.full_name,
                "Image": p.image,
                "Link": p.link
              };
              return {
                "x": webMercator.x,
                "y": webMercator.y,
                "attributes": attributes
              };

so basically an array with the following structure.

{
                "x": 120,
                "y": -32,
                "attributes": {

"Caption": "caption",
                     "Name": "a name",
                     "Image": small.jpg,
                    "Link": "http link"

}
              };
