Animated Bars – Uncertainty

This is an example of a chart created using animated-bars. One possible use for an animated bar chart is an animated uncertainty chart, which can be used to show how a set of estimates surrounded by a margin of error might also have looked given their statistical uncertainty. This chart starts with a given set of estimates. Clicking on the chart animates it with a generator that yields normal random variables for each data point with a standard deviation representing their margin of error.
