Help needed - displaying JSON in charts/graphs

Hey folks.

Anyone here with good JSON experience in Xcode?

I've tried a few tutorials, and I can get them to work, but I'm struggling to really convert the practice to my own stuff.

The thing is I've got a webservice which returns JSON, and I'm really struggling to call and display the output.

For example here's one of the data sets I can call: http://182.50.143.15/charting?type=b...singapore,food

I can't seem to figure out how to call it and display it in a text label, let alone in a chart (which is my ultimate goal). I'd love it if anyone can help me in terms of how to plot it into graphs/charts, but at this point I'd be thankful for even just a simple text label being able to display the JSON data first.

Also does anyone know a good library/framework to use for displaying JSON data in a chart/graph/etc? Thanks.

Do you know about the NSJSONSerialization class?

Well, it'll definitely help you to convert your JSON into arrays / dictionaries for your code to use.

P.S. You said you've tried a few tutorials on JSON. Which ones? (URLS, please, if possible). When referencing third-party resources, it's courteous to provide as much detail about the resources as possible.
