Mother's ethnicity

For all those graphs I wished they would offer the possibility to have them in percentages. Right now the graphs are not helpful since knowing that 34 hispanics and 212 Northern Europeans have only a few patches does not tell me anything. The only thing that it tells me is that there are more northern europeans listed in the database than hispanics. If on the other hand I could see that 30% of northern europeans and only 24% of hispanics have few patches (which is the case but I had to work it out on my calculator, which is very time consuming if you are looking at a lot of data) then the graph would give me valuable insights. I love the possibilities with this project, but I would like to see some issues fixed for it to be helpful.
