Problem 1: Can you think of any other graphs that would be useful, or other kinds of features that could be derived from the data we have? Search online for Titanic dataset feature engineering ideas, and see if you can use the copy-paste-tweak method to get any of the ideas you find to work. This can be new columns you create, more graphs that explore other relationships, etc. Just be sure to leave meaningful comments on what you are trying to do and what the new graphs show us.
Problem 2: In a final comment/comment chunk at the end of your script: summarize what you learned through this process of exploring the Titanic dataset. What features seems to be strongly related to survival on the Titanic? Did you notice any interesting relationships between features besides survival? Did you notice any data quality issues along the way that may need to be corrected in the data cleaning steps later on?
