Rotate text around a circle

dbj44

I want to rotate some text (numbers) positioned around a circle so that it looks like this:

enter image description here

In order to apply the rotation, I've tried this: .attr("transform", function(d, i) { return "rotate(" + (-90 + ((360 / dial.length) * i)) + ", 135, 135)"; });but it throws everything away.

Here is a fiddle .

@GerardoFurtado's solution is fine, but the code can be greatly simplified if everything is placed at the origin.

Feel free to accept his answer. I just wanted to point out some efficiencies.

var width = height = 300,
    circleRadius = (width / 2) * .8,
    digitRadius = (width / 2) * .9;

svg = d3.select("body")
  .append("svg")
  .attr("width", width)
  .attr("height", height)
  .append("g")
  // Everything inside the group is centred at the origin and we use
  // a transform on the group to move the whole group to the centre of the SVG
  .attr("transform", "translate(" + width / 2 + "," + height / 2 + ")");

svg.append("circle")
  .attr("r", circleRadius)
  .style("fill", "none")
  .style("stroke", "black");

dial = [1, 2, 3, 4, 5, 6, 7, 8];

// Position text at X=radius, Y=0 and rotate around the origin to get final position
svg.selectAll("text")
  .data(dial)
  .enter()
  .append("text")
  .attr("x", digitRadius)
  // tweak digit Y position a little to ensure it's centred at desired position
  .attr("y", "0.4em")
  .text(function(d, i) { return d; })
  .attr("transform", function(d, i) { return "rotate(" + (-90 + ((360 / dial.length) * i)) + ")"; });

Is there a way to rotate the text around a circle (or circles)?
