Tell us what’s happening:

I really don’t understand this particular challenge. Need some help please…

Your code so far


<body>
<script>
  const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9];

  const w = 500;
  const h = 100;

  const svg = d3.select("body")
                .append("svg")
                .attr("width", w)
                .attr("height", h);

  svg.selectAll("rect")
     .data(dataset)
     .enter()
     .append("rect")
     .attr("x", (d, i) => i * 30)
     .attr("y", (d, i) => h - 3 * d)
     .attr("width", 25)
     .attr("height", (d, i) => 3 * d)
     .attr("fill", "navy");

  svg.selectAll("text")
     .data(dataset)
     .enter()
     // Add your code below this line




     // Add your code above this line
</script>
<body>

Challenge: Add Labels to D3 Elements

You have to be specific about what you don’t understand to be easily helped.
The task requires you to

  1. Append text nodes to the svg . Which you can accomplish by
    .append(text)

  2. Add attributes for the x and y coordinates. Which you can accomplish by
    .attr('x', (d, i) => i * 30)

    .attr('y', ??) //Figure out for y because it is the gist of the task

  3. Use the D3 text() method to set the label equal to the data point value.
    .text( d => d)
