Those graphs should really be column or row graphs. Their is no such things as '7.5' characters, so it is kind of misleading. It would also make it much easier to see interpret information, like the fact that 16 is the longest password used. As for the Character Types, that data isn't even connected, so a line graph doesn't fits even less.
