ArcGIS js API - possible to get data map points from an external web service?

I'm very new to ArcGIS and I'm currently exploring the js API. I haven't seen documentation for this but can i use a json datasource (returned from an ajax call) as the data items/points for my map? Can anyone point me to an example?

Solution

  • If you don't have any Map Service (ArcGIS, WMS, KML, etc) but just a list of geometries fetched from somewhere else you must use a GraphicsLayer. You can use the default GraphicsLayer of the map or add another GraphicsLayer.

    for each geometry:

    map.graphics.add(new Graphic(geometry, symbol));
