Made a bar chart in R and then D3 recreating this NY Times bar chart on ESPN network's relative monthly price.
Another recreation (rather attempted recreation) of a NY Times graphic, this time with interactivity (click on a team and the line will change).
A mapping exercise using a California county shapefile and joining it with state demographic data to show the percent Hispanic population per county. Also my first lesson in saving my R code, never to be forgotten.
We did a "quick" (nowhere close to breaking news quick) exercise using a dataset that listed by county where guns recovered in Chicago came from. The link above is the result of the R code, and here is the code itself.
We spent some of the final weeks in class reporting and producing our own final project. I chose to focus mine on missed votes in Congress, particularly testing the assumption that legislators prioritize campaigning over making law. Lots of R and D3 went into this, link to R code.
