data

</script> <p>Once we have a selection, we can apply various operators to the selected elements. For example, we might change the fill color using <a href="https://github.com/mbostock/d3/wiki/Selections#style">style</a>, and the radius and the <em>y</em>-position using <a href="https://github.com/mbostock/d3/wiki/Selections#attr">attr</a>:</p> <div class="chart" id="chart-3"> <pre class="code">circle.style("fill", "steelblue"); circle.attr("cy", 90); circle.attr("r", 30); </pre> <button>run</button>  <script type="text/javascript">

script


  (function() {
    var svg = d3.select("#chart-3").append("svg")
        .attr("width", w)
        .attr("height", h);

circle


    var circle = svg.selectAll(".little")
        .data(data)
      .enter().append("circle")
        .attr("class", "little")
        .attr("cx", x)
        .attr("cy", y)
        .attr("r", 12);

select


    d3.select("#chart-3 button").on("click", function() {
      circle.style("fill", "#aaa").attr("r", 12).attr("cy", y);
      circle.transition().duration(500).delay(0).style("fill", "steelblue");
      circle.transition().duration(500).delay(500).attr("cy", 90);
      circle.transition().duration(500).delay(1000).attr("r", 30);
    });
