Reusable waffle charts

Reusable waffle charts

Basic waffle charts using Mike Bostock's [http://bost.ocks.org/mike/chart/](reusable charts) convention. Waffles are configurable, as you can see below:

var waffle = new WaffleChart()
  .selector(".chart")
  .data(data)
  .useWidth(false)
  .label("Value of producers' sales in 2013, in thousands of dollars")
  .size(12)
  .gap(2)
  .rows(20)
  .columns(60)
  .rounded(true)();

Each configuration parameter is as follows:

• selector: The container in which to draw a waffle chart.
• data: The data to use when drawing the waffle.
• useWidth: Whether to constrain the waffle to the container's width.
• label: A label to pass to the waffle. Optional.
• size: Width and height of each waffle "block", in pixels. Optional. Default: 6.
• gap: Gap between each block, in pixels. Optional. Default: 2.
• rows: Number of rows of blocks. Optional. Default: 50.
• columns: Number of columns of blocks. Optional. Default: 100.
• rounded: Whether or not to draw the blocks as circles instead of squares. Optional. Default: false.
