title: create d3.js axes without numbering
body: <p>Is there a way to create a d3.js axis without any kind of numbering? Tickmarks are ok but just no numbers at all. Currently I'm creating my d3.js axis with the code below. Thanks in advance.</p>
  
  <pre><code> // create Axis
    svg.selectAll("axis")
        .data(d3.range(angle.domain()[1]))
      .enter().append("g")
        .attr("class", "axis")
        .attr("transform", function(d) { return "rotate(" + angle(d) * 180 / Math.PI + ")"; })
      .call(d3.svg.axis()
        .scale(radius.copy().range([0,0]))
        .ticks(1)
        .orient("left"))
      .append("text")
      .style("color", "white") 
        .attr("y", 
          function (d) {
            if (window.innerWidth &lt; 455){
              console.log("innerWidth less than 455: ",window.innerWidth);
              return -(0);
            }
            else{
              console.log("innerWidth greater than 455: ",window.innerWidth);
              return -(0);
            }
          })
        .attr("dy", "0em");
  </code></pre>
