I am using albersUSA projection to display a map. 
I want to add the name of the states to each state.

This is what I tried, and i can see the names of the states in the source, but I don't see them rendered.
What am i doing wrong?

```
var width = 1060,
height = 600,

var svg = d3.select("body").append("svg")
    .attr("width", width)
    .attr("height", height);

svg.append("rect")
    .attr("class", "background")
    .attr("width", width)
    .attr("height", height)
    .on("click", click)
    .on("mousemove", mousemove);

var g = svg.append("g")
    .attr("transform", "translate(" + width / 2 + "," + height / 2 + ")")
    .append("g")
    .attr("id", "states");

var projection = d3.geo.albersUsa()
    .scale(width)
    .translate([0, 100]);

var path = d3.geo.path()
    .projection(projection);

draw();

function draw(){

  d3.json("readme.json", function(json) {
    g.selectAll("path")
    .data(json.features)
    .enter()
    .append("path")
    .attr("d", path)
    .append("svg:text")
    .text(function(d){
        return d.properties.name;
    })
    .attr("x", function(d){
        return -path.centroid(d)[0];
    })
    .attr("y", function(d){
        return  -path.centroid(d)[1];
    });

  });
}

```
