Filtering in JavaScript with radio button using D3 library

I am trying to use a set of radio buttons to filter between data on a D3 scatter plot diagram. My scatter plot diagram is based on http://bl.ocks.org/mbostock/4063663. I have only modified the code to fit my data needs. The code in the link is very close to what I have.

The code in my CSV file is arranged in the following way.

DataType1,DataType2,DataType3,DataType4,
  1,2,3,4
  1,2,3,4
  1,2,3,4
  1,2,3,4
  1,2,3,4

I solved it, here is my code:

Open<input type="radio" name="Status" id="radio-open" value="Open" onClick="window.location.reload()" />
    Closed<input type="radio" name="Status" id="radio-closed" value="Closed" onClick="window.location.reload()"/>
    Clear<input type="radio" name="Status" id="radio-clear" value="Clear" onClick="window.location.reload()"/>

And:

  if (!document.getElementById('radio-clear').checked) {
    if (document.getElementById('radio-open').checked) {
      data = data.filter(function(d) { return d["Status"] == "Open"; })
    }
    else if (document.getElementById('radio-closed').checked) {
      data = data.filter(function(d) { return d["Status"] == "Closed"; })
    }

}
