title: D3 Mouseover for multiple elements
body: <p>I am trying to highlight some of my svg elements when mouseover at a specific element.</p>
  
  <p>So, i got elements like one big circle, small circles for every node, a line for every node, a text for every node.</p>
  
  <p>What I can do is something like this:</p>
  
  <pre><code>on("mouseover", function(d) {
        d3.select(this)
        .style("fill", '#0da4d3');})
  </code></pre>
  
  <p>But I want to use the mouseover method for more than the element in which I am adding the code.</p>
  
  <p>For example, when selecting the big root circle, I want to use mouseover for rootcircle, all texts, the lines and all small circles.</p>
