This web app takes raw, detailed play-by-play data scraped from http://pro-football-reference.com and uses plotly to create dynamic illustration of offensive performance. How often does the offense get a first down on 1st and 10. Do they often end up in 2nd/3rd and long situations? Looking at offensive performance with this kind of visual aid can provide an instant and intuitive understanding that can be difficult to illustrate with numbers alone.
