I have some point data which store as JSON.As follow: [["Lat":"12.12","Long":"23.23","ZValue":"123"],...].

I tried to interpolate them as contour line and displayed them on my website ? I do know how to interpolate data in ArcInfo,so I tried to publish a geoprocessing task and using ArcGIS JavaScript API to generate them but it failed to published to ArcServer.enter image description here

However,I search for a long time if there exits some other solution but found nothing about how to implement this.

Thanks for any suggestion!
