Statistics with a Better Histogram

Here's yet another version of the statistics program we've been working with throughout the last week. Yesterday's version of the statistics program included a horizontal histogram that looked like this:

Frequency of Values:
1  | *****
2  | *************
3  | *******************
4  | ****************
5  | ***********
6  | ****
43 | *
62 | *

For this version, we'll print a vertical histogram that looks like this:

 †††††* †††††* †††††* †††††* †††††* †††††*†* †††††*†*†* †††††*†*†*†††††††*†††††*†††††* †††††*†*†*†††*†*†*†††††*†††††* †††*†*†*†*†††*†*†*†††††*†††††* †††*†*†*†*†††*†*†*†††††*†††††* †*†*†*†*†*†*†*†*†*†††††*†††††*††* †*†*†*†*†*†*†*†*†*††*††*††*††*††*††*††* --------------------------------------- †1†2†3†4†5†6†7†8†9†12†23†25†34†37†39†42 ...
