Unclear Data Type

[YellowBlueFrog]

On your webpage you mention about how the only things a web developer would need to do in order to implement your CodeFlower would be import CodeFlower.js and d3.js, create a div like so <div id="visualization"></div>, and to put the following code inside of script tags:
var myFlower = new CodeFlower("#visualization", 300, 200);
myFlower.update(jsonData);

I have done all of the following and even have a working .json file (I tested it on your webpage). My question is how would I tell myFlower to get info from my .json file? I already tried replacing 'jsonData' with a String address to my .json file and that did not work.
Thank you in advance!
