Histogram Bin Sizes

Histograms are a remarkable way to "see" data. And, carefully constructed, a histogram can reveal a lot of information. Nevertheless, some care must also be taken when making a histogram. In particular, how the bin size is selected makes a big difference. (See some data about Old Faithful eruption times for a nice example).

You can see this effect for yourself with any data you like. Enter some data in the form below and "play" with the bin sizes. Do different bin sizes give you a different impression of the data?
