In case the labels aren't clear: "No" and "Yes" refer to survival.

All the children who died were in third class.

Here's a view with bars, for comparison with the initial bubble view. Note how some details are harder to see (the female crew members who died, for instance) in this view, but ratios between overall bar sizes are clearer.

Wow, the new matrix plot is really cool!

I was told by a Titanic buff that the only girl in the first class actually did not survive because her parents did not let her on board the life raft without them. The kids in third class probably died for different reasons, though.
But this is a great visualization for categorical data, much more useful than the treemap (at least I haven't figured out how to use colors there)! |

Hi, EagerEyes, where did you get this data set from?

When you look at the proportion who survived, by age and class (as in my visualization), a few things come out. Looking at the pie charts, it appears that class was more important in determining which women were saved than which men. The proportion of males saved was higher for first class passengers than for second and third (34% as compared to 14% and 17%), but the percentage point discrepancy was much bigger for women (97% for first as compared to 87% and 46% for second and third). (In proportional terms, the role of class was equally large -- you were roughly twice as likely to survive if you were in first class than if you were in third class.) Also, I found it interesting that the proportion of crew members to survive was higher than the proportion of third class passengers, for both genders. With the men I imagine some crew members were piloting life boats, and maybe for both genders the crew members knew more about the urgency of the situation sooner and were therefore more motivated to get in lifeboats.
