I wanted to use R to explore how to access and visualize census data, home value data and school rating data using Indianapolis metro area as an example. My learning objectives here are to learn how to use R to:
- Make choropleth maps at zip code level
- Process data in XML or JSON format that is returned when using API provided by websites (here I chose Zillow and education.com as an example)
The full R code along with explanation can be found here.
The maps of median age, median household income, median home listing price/value per sq feet and school rating overlaid over Indianapolis map is shown below
