Communicating uncertainty

Can interactive graphics help? In this experimental visualisation, a single estimated point (x=10, y=10) carries some uncertainty. By clicking on the button below, a series of probable values appears. These might be bootstrapped values, draws from a posterior joint distribution, or just representing a theoretical sampling distribution. By clicking on the chart region, you can see the probability of the true value being as far away as your point, or further. (My wording is unapologetically Bayesian.)
