Yihui Xie adb444a60f the original hello-world example makes little practical sense -- it is unclear what really changed when moving the slider, especially when obs is large (we always see a "bell-shaped" histogram)
let's make the number of bins reactive instead; now it is very clear what the slider really controls

a histogram with different number of bins also serves as a good demo of the property of histograms (small bins --> small variance + large bias)
