Histogram in Google Spreadsheet

It's not easy to make a histogram in google spreadsheets without replicating data. The "countif" function would be great, except it only allows very simple criteria. However, there's a workaround:

The Filter() function returns an array, which can be operated on like any other set of cells.

It's still not easy to make a nice-looking histogram, but the output of this process is at least usable.
