title: d3 replacing semicolon with comma
body: <p>Hoping someone way clever than me can quickly help solve this. I have csv files coming in with a semicolon seperator. it cant read the headings:</p>
  
  <pre><code>d3.csv("file.csv", function(error, data) {
     data.forEach(function(d) {
         d.date = parseDate(d.date);
         d.value2 = +d.value2;
         d.value1 = +d.value1;
     });
  </code></pre>
  
  <p>I've tried adding something like data.replace(/\s*;\s*/g, ",") but doesnt work.</p>
  
  <p>Appreciate the help.</p>
