title: Selecting element at coordinates in SVG
body: <p>So, I have a SVG that was exported from Adobe Illustrator (the illustrator file is no longer available).  I also have a csv with data and coordinates <code>(x1, y1,x2, y2)</code>.  I've <code>ctrl+f</code>'d for these values in the SVG and none of them are in there.  My guess is this is because adobe illustrator moved everything (although I could be wrong). </p>
  
  <p>My question is if there's a way, using d3 or some other library to get the element (or elements, I know SVG is multilayered) at a given coordinate.  My goal here is to use the CSV's data to generate a tooltip.  When a user hovers over the elements at the coordinates given in the svg, it should drop down with some data from the csv.  Any other suggestions on how to accomlpish this?</p>
