javascript - Running TreeData example D3JS

Question

I am trying to test the example of the DataTree of D3Js and I just copied and pasted the code in: http://bl.ocks.org/d3noob/8329447 . I saved the TreeData.json in my C drive and changed the d3.json("treeData.json", function(error, treeData) to d3.json("C: reeData.json", function(error, treeData) and I get the error of "Cannot read property '0' of undefined" by looking at the javascript console. But once I hard code the json file into the program it works fine. Can somebody help me with that?

Answer 1

The issue is that web pages can't read your C drive you need to put the relative path to your json file in you project.

Easiest way to do this is to treeData.json file in the project folder with your treeData.json
