title: Breaking a SVG Line
body: <p>I work with SVG and d3js and I want a line with values like:</p>
  
  <p>0,10 -
  10,20 -
  20,25 -
  30,40 -
  40,50</p>
  
  <p>So, for example, I want a line with these points but between the point "20,25" and "30,40" I want nothing (or a line but transparent). And I don't want to have two lines.</p>
  
  <p>Is there a way to do that?</p>
