Add names of the states to a map in d3.js

OK for anyone wondering, this is how I managed to do it:

function draw(){

  d3.json("readme.json", function(json) {
    g.selectAll("path")
    .data(json.features)
    .enter()
    .append("path")
    .attr("d", path)
    .on("click", click);

    g.selectAll("text")
    .data(json.features)
    .enter()
    .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];
    })
    .attr("text-anchor","middle")
    .attr('font-size','6pt');


  });
}
