How can I join the table to the features in a web map, and symbolize the polygons using attributes from the table? The joined table must be specified within the web application (rather than hard-coded via ArcMap) since the statistics will be derived on-the-fly and will be specific to each user.
I need the ability to change the symbology on-the-fly, for example by choosing a different crime statistic to map, in which case the map should update immediately.
Using ArcGIS Server 10.1 the REST API supports table joins. Are there any sample scripts which step through how to set this up?
Can the same thing be achieved using FOSS software?
Thanks. (This is a modified version of my earlier question since that hasn't yet received any responses)
