you had me hooked when I saw it was based on the Titanic - Interesting to see how the survival rate varied across the passenger profile
couple of suggestions -
it felt like a couple of the charts were redundant - or could be combined into a single chart -
the difference in the data filtered with the menu on the first page was not impactful - the point was better made on the second set of charts
also I was left wondering if there was other data about the survivor list that ould have added depth to the presentation - like their nationality, home city/country, reason for travel - also what about the crew?
If you had their home city for example incorporating mapping that may have included the day to day travel of the ship could be interesting -
Just some thoughts
