Use d3.json function with variable instead of URL

Question

Hello I have a jquery ajax call that returns json data from an api.

I turned that json into a variable and want to use it in d3.json.

It isnt taking the variable name, I think because its expecting a url instead of a variable name.

Here is the code:

jQuery.ajax({
    type: "GET",
    url: myurl.com,
    success: function(effects)
    {
        var dataArray = effects;

            d3.json(dataArray, function (data) { //error here
                console.log(data);
            });
    }
});

Those of you good with d3, can you help me get the json data into the d3.json function?

Thanks

I think there is a slight misconception on what both methods actually do. d3.json() is not just for parsing; it will request the JSON resource and parse it, whereas jQuery.ajax() only requests the resource without parsing it. When using jQuery.ajax() you need to use the native JSON.parse() to parse the JSON string, not d3.json()**! — altocumulus

d3.json already does the AJAX request for you, so I'd just use that if possible. — ggorlen

I think you've got the data from API which you called effects. I suppose that the effects are in json format like "key":"value" paires, you can try var jsonVariable = effects["key"] to get the value.
