Do you have any ideas on how to display and compare probabilities? For example, I am trying to show the likelihood that obese children become normal weight, overweight, or obese at some later time point (probabilities sum to 100%) and compare that to the probability that overweight children become normal weight, overweight, or obese at some later timepoint. I could just do bar graphs, but was wondering if there were some other unique way to show the data.

This might be useful to you:

You could use that for sure, albeit slightly modified.
Perhaps one theater of obese children. Show in different colors the seats representing those who become normal weight, overweight and obese. Then do the same for the overweight group, using same colors. If there's an obvious pattern there this should highlight it.
I like the technique because people can easily relate to it and "get the message".

thanks so much Tim. That's really helpful. I will give it a try

At first I thought this idea would be interesting, but after thinking about it some more it seems that the ink to data ratio is absurdly high for the use the authors describe.
Are people so innumerate that they need 2 grids of 1000 squares each to compare just two data points?
I do like Tim's idea of filling in all the seats by color for each subgroup then comparing two theaters. Its not a pie chart!
