How can I add square brackets to my json data source?

[danharr]

I am practicing making a real time visual using angular and d3.js.  In the below bl.ock things work as expected when data is obtained using $http.get('data.json'):

http://bl.ocks.org/danharr/10540505

The data source looks like so:

[{"name":"alan" , "age":8},
{"name":"alan2" , "age":18}]

But most feeds of JSON that I'm coming across look more like:

{"name":"alan" , "age":8},
{"name":"alan2" , "age":18}

i.e. no opening and closing square bracket.  Is there a way to have http.get read the data despite the lack of square brackets?

Thanks!

Is your data source not giving you valid json? If not, can you fix that
instead? There's probably bigger bugs lurking if its not passing a
standard format. If you give us a link to one of these strange feeds
(and I do think they're strange; proper json will not be like you show)
we can maybe tell if there is something misspecified about your calls.

If the only bug is literally just the lack of [ ] (if!), in the worst
case, you can set data="[" + data + "]" and parse it with JSON.parse. I
see where you are confused a bit though; $http.get is not a d3 call; it
is an AngularJS call. The docs for it say
> If JSON response is detected, deserialize it using a JSON parser.

To go this route you need to disable that deserialization. The docs say
you can tell Angular to turn off the deserialization with
$http.get('data.json', {transformResponse: []})

thanks for the guidance

An example of data I'm trying to use which I feel is missing square brackets (though maybe not) is:

http://api.openweathermap.org/data/2.5/weather?q=London,uk

Unless I save this data manually,say into mydata.json, and add square brackets I can't read in the data.

I'll read up on transformResponse and reply if I get any success

Thanks!
