title: For d3js, has anybody created a mapping of types of input data to possible types of output charts?
body: <p>Is there already a way to automatically generate possible samples of a d3js output graph based on the nature of the input?</p>
  
  <p>I'm trying to tabulate different charts on the d3js gallery page <a href="https://github.com/mbostock/d3/wiki/Gallery" rel="nofollow">d3js gallery</a> to the nature of input data.  i.e. if there were two columns of data and one of them is a number, then we could generate a bar graph or a line graph.</p>
  
  <p>Eg.
  Bar Graph; {columns:2, yaxis: number, xaxis: number/date/nominal} 
  <a href="http://bl.ocks.org/metormote/6392996" rel="nofollow">SpeedoMeter</a>; single number value</p>
  
  <p>At least has somebody already got a start on this?</p>
