d3 heatmap box should create on boolean value

i want to build a heatmap based on boolean value array like :

and result should be :

I have found this :

  var margin = { top: 50, right: 0, bottom: 100, left: 30 },
      width = 960 - margin.left - margin.right,
      height = 430 - margin.top - margin.bottom,
      gridSize = Math.floor(width / 24),
      legendElementWidth = gridSize*2,
      buckets = 9,
      colors = ["#ffffd9","#edf8b1","#c7e9b4","#7fcdbb","#41b6c4","#1d91c0","#225ea8","#253494","#081d58"], // alternatively colorbrewer.YlGnBu[9]
      days = ["Mo", "Tu", "We", "Th", "Fr", "Sa", "Su"],
      times = ["1a", "2a", "3a", "4a", "5a", "6a", "7a", "8a", "9a", "10a", "11a", "12a", "1p", "2p", "3p", "4p", "5p", "6p", "7p", "8p", "9p", "10p", "11p", "12p"];


  d3.tsv("data.tsv",
    function(d) {
      return {
        day: +d.day,
        hour: +d.hour,
        value: +d.value
      };
    },
    function(error, data) {
      var colorScale = d3.scale.quantile()
          .domain([0, buckets - 1, d3.max(data, function (d) { return d.value; })])
          .range(colors);

      var svg = d3.select("#chart").append("svg")
          .attr("width", width + margin.left + margin.right)
          .attr("height", height + margin.top + margin.bottom)
          .append("g")
          .attr("transform", "translate(" + margin.left + "," + margin.top + ")");

      var dayLabels = svg.selectAll(".dayLabel")
          .data(days)
          .enter().append("text")
            .text(function (d) { return d; })
            .attr("x", 0)
            .attr("y", function (d, i) { return i * gridSize; })
            .style("text-anchor", "end")
            .attr("transform", "translate(-6," + gridSize / 1.5 + ")")
            .attr("class", function (d, i) { return ((i >= 0 && i <= 4) ? "dayLabel mono axis axis-workweek" : "dayLabel mono axis"); });

      var timeLabels = svg.selectAll(".timeLabel")
          .data(times)
          .enter().append("text")
            .text(function(d) { return d; })
            .attr("x", function(d, i) { return i * gridSize; })
            .attr("y", 0)
            .style("text-anchor", "middle")
            .attr("transform", "translate(" + gridSize / 2 + ", -6)")
            .attr("class", function(d, i) { return ((i >= 7 && i <= 16) ? "timeLabel mono axis axis-worktime" : "timeLabel mono axis"); });

      var heatMap = svg.selectAll(".hour")
          .data(data)
          .enter().append("rect")
          .attr("x", function(d) { return (d.hour - 1) * gridSize; })
          .attr("y", function(d) { return (d.day - 1) * gridSize; })
          .attr("rx", 4)
          .attr("ry", 4)
          .attr("class", "hour bordered")
          .attr("width", gridSize)
          .attr("height", gridSize)
          .style("fill", colors[0]);

      heatMap.transition().duration(1000)
          .style("fill", function(d) { return colorScale(d.value); });

      heatMap.append("title").text(function(d) { return d.value; });

      var legend = svg.selectAll(".legend")
          .data([0].concat(colorScale.quantiles()), function(d) { return d; })
          .enter().append("g")
          .attr("class", "legend");

      legend.append("rect")
        .attr("x", function(d, i) { return legendElementWidth * i; })
        .attr("y", height)
        .attr("width", legendElementWidth)
        .attr("height", gridSize / 2)
        .style("fill", function(d, i) { return colors[i]; });

      legend.append("text")
        .attr("class", "mono")
        .text(function(d) { return "≥ " + Math.round(d); })
        .attr("x", function(d, i) { return legendElementWidth * i; })
        .attr("y", height + gridSize);
  });

with this example i have successfully place the labels but unable to draw boxes. I have make many charts in nvd3 rhis is first chart in d3.js. anybody help?
