Text on vertical bars not showing using d3.js

Question

I am trying to generate bar chart using d3.js.But my code is not showing the text i have appended on rect.I call a function that displays the the bar chart.My code is as follows my code:

function renderChartVertical(data)
{
    var margin = {top: 20, right: 20, bottom: 150, left: 100},
    width = 600 - margin.left - margin.right,
    height =400 - margin.top - margin.bottom;


var x = d3.scale.ordinal().rangeRoundBands([0, width], .05);

var y = d3.scale.linear().range([height, 0]);

var xAxis = d3.svg.axis()
    .scale(x)
    .orient("bottom");


var yAxis = d3.svg.axis()
    .scale(y)
    .orient("left")
    .ticks(10);

var tip = d3.tip()
.attr('class', 'd3-tip')
.offset([-10, 0])
.html(function(d) {
  return "<strong>Value:</strong> <span style='color:blue'>" + d.value + "</span>";
});

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 + ")");
svg.call(tip);
  x.domain(data.map(function(d) { return d.key; }));
  y.domain([0, d3.max(data, function(d) { return d.value; })]);

  svg.append("g")
       .attr("class", "barsLables")
      .attr("transform", "translate(0," + height + ")")
      .call(xAxis)
    .selectAll("text")
      .style("text-anchor", "end")
      .attr("dx", "-.5em")
      .attr("dy", "0.1em")
      .attr("transform", "rotate(-45)" );

  svg.append("g")
      .attr("class", "gridLineLabels")
      .call(yAxis)
    .append("text")
      .attr("transform", "rotate(-90)")
      .attr("y", 6)
      .attr("dy", ".71em")
      .style("text-anchor", "end")
      .text("Value ($)");

  svg.selectAll("bar")
      .data(data)
    .enter().append("rect")
    .attr("class", "bars")
      .attr("x", function(d) { return x(d.key); })
      .attr("width", x.rangeBand())
      .attr("y", function(d) { return y(d.value); })    
      .attr("height", function(d) { return height - y(d.value); })
      .on('mouseover', tip.show)
      .on('mouseout', tip.hide);

  svg.selectAll("rect")
.append("text")
.attr("class", "below")
//.attr("x", 12)
//.attr("dy", "1.2em")
.attr("text-anchor", "end")
.text(function(d) { return d.value; });

//  svg.selectAll("bar")
//  
//  .attr("height", 0)
//  .transition()
//  .delay(100000000) ;     
}

In your Question It looks like you are trying to append text in side rect well that is not possible

If you want add text on vertical bar then

• create 'g' group element
• first append rect element in group
• second append text element in group

<svg xmlns="http://www.w3.org/2000/svg">
<g>
  <rect x="0" y="0" width="100" height="100" fill="red" ></rect>
  <text x="0" y="10" font-family="Verdana" font-size="55" fill="blue" > Hello </text>
</g>
</svg>
