<h2> I have taken only QBs from schools in the Big Five conferences, coloring the marks by conference.</h2>
<h3> Selecting any one conference (among SEC,ACC,Big 12,Pac 12,Big Ten) and clicking on that respective dot on the graph, highlights that conference and makes all other conferences inactive for some time. By this audience can get the count in each conference.</h3>
