Thanks Taha and Howard! Looks like I have some more learning to do, which is always great. BTW, I'm on T5.3.6.
Howard, for my purposes the JSON payload for the visualization needs to be generated at runtime when the user clicks (I'll eventually have dozens of clickable links, each one a costly calculation)--your solution sounds like the json is getting pre-calculated (unless I am interpreting it wrong, which is likely) I was trying one of Taha's old examples that seemed similar ( http://apache-tapestry-mailing-list-archives.1045711.n5.nabble.com/Updating-a-page-with-a-JSONObject-td3339940.html ) But I'm getting an error with that. Possibly because I'm trying to trigger the Ajax response through an eventlink I added to the TML, with no Zone. Do I need to make use of a zone component at all? I'm getting an error of "Page must be specified before initializing for partial page render."
