This variation of a bivariate area chart uses clipping to alternate colors. When New York is warmer than San Francisco, the difference between the two is filled in green. When San Francisco is warmer, the difference is filled in red. A similar technique was used by William Playfair all the way back in 1786.

The easiest way to transition between pie charts with differently-sized datasets (while maintaining object constancy) is to set the missing values to zero.

function type(d) {
  d.apples = +d.apples || 0;
  d.oranges = +d.oranges || 0;
  return d;
}

This variation of a donut chart demonstrates how to update values with an animated transition. Clicking on the radio buttons changes the displayed metric.
