Data Visualization of FIFA 15's Player Ratings with R and Java

• Using [fifaguide's Developer API] (http://tools.fifaguide.com/develop.php), JSON files are retrieved and parsed with Java's JSON API in a separate Java file (see src for ratingRetriever).
• The data (about 19,000 ratings) is then written onto multiple .csv files
• With ggplot2 and R's built in capabilities, this data is then visualized into 7 distinct histograms, density plots, and dotplots.

Frameworks and Languages used:

• [ggplot2] (http://ggplot2.org/) for the complex graphs
• [fifaguide's Developer API] (http://tools.fifaguide.com/develop.php) for retrieving ratings
• [Google's Java JSON library] (https://github.com/google/gson) for parsing the JSON data
• Java for the data parsing and R for data visualization

How to Run:

• In your R console, use the source() function to run each of the R scripts
• Make sure that the files are in your working directory using dir()
• If source() does not work, then run each script line by line, making sure library(ggplot2) is ran
