Homework 3 - Joining data

Overview: The goal of this assignment is to join two (or more) sources of data to create a single visualization, providing insight that could not be obtained from a single dataset alone. This is a core task in data analytics and visualization, as we often want to show relationships between different features of the world (though be sure to avoid the dreaded spurious correlations!)

Requirements:

• Choose two or more public datasets each with at least 2 variables including at least one shared variable to join on.

  • As before, there are no strict restrictions on what datasets you choose, but you should aim to choose a datasets that are unique, insightful and the require minimal preprocessing.

  • There are no restrictions on what variable(s) you choose to join on. Common choices might be: time (day, month, year etc.), geography (city, county, state, country) or entity (school, company, etc.).

  • You may need to pre-process each dataset to ensure alignment of the joining variable.

• Create a visualization involving at least 3 variables from across the two datasets. The specifics of the visualization are up to you, but should aim to be relevant and insightful.

• Include a descriptive caption explaining the context.

• Cite and provide a link to the source of each dataset used. Specify which variables came from each dataset.

• Aim to make each visualization polished and legible.
