title: D3 time series heatmap
body: <p>I am trying to make a heatmap using d3 which on x axis a time series, on y a number and the color is the value for the cell. The data is loaded based on the input and the domain and range can change on different input. I was not able to find such example. Does anyone have an idea how I can create that?</p>
  
  <p>Thanks</p>
