javascript - Very simple tutorial example of D3.js not working

I'm kind of new to D3.js. I'm reading Getting Started with D3 by Mike Dewar. I tried the very first example in the book, and it doesn't work. I've been tearing my hear out over this. What is wrong with my code here?

In the <head> section:

<script src="http://mbostock.github.com/d3/d3.js"></script>
<script>
   function draw(data) {
    "use strict";
   d3.select("body")
      .append("ul")
      .selectAll("li")
      .data(data)
      .enter()
      .append("li")
         .text(function (d) {
            return d.name + ": " + d.status;
         });
      }
</script>

In the <body>:

<script>

    d3.json("flare.json", draw);

</script>

And the JSON file:

[
{
    "status": ["GOOD SERVICE"],
    "name": ["123"],
    "url": [null],
    "text": ["..."],
    "plannedworkheadline": [null],
    "Time": [" 7:35AM"],
    "Date": ["12/15/2011"]
}
]

If you're using Chrome, it may prevent you from opening the file properly because of cross domain security restrictions. Try Firefox to see if that's the case (it will probably let you load the file correctly).

If that is the problem, you will want to install a local web server like WAMP (if you're running Windows) or follow instructions on the wiki page here: https://github.com/mbostock/d3/wiki

Good luck
