Starting Points w/ Data

I created this to easily share a list of bl.ocks w/ links.

<!DOCTYPE html>
<head>
  <meta charset="utf-8">
  <script src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.5.5/d3.min.js"></script>
  <style>
    body { background:#8d9ca4;margin:0;position:fixed;top:0;right:0;bottom:0;left:0; }
    svg {width: 100%; height: 100%; }
    image {cursor: pointer}
    div {color: white; margin-left: 10; margin-top: 15}
  </style>
</head>

<body>
  <div>Click on a thumbnail to go to see that block on bl.ock.org</div>
  <script>
    var margin = {top: 20, right: 10, bottom: 20, left: 10};
    var width = 980 - margin.left - margin.right;
    var height = 500 - margin.top - margin.bottom;
    var svg = d3.select("body").append("svg")
    	.attr("width", width + margin.left + margin.right)
     	.attr("height", height + margin.top + margin.bottom)
    	.append("g")
      		.attr("transform", "translate(" + margin.left + "," + margin.top + ")");
       
    var startingPoints = [
