<h1>James Eanes - Visualization Implementation 9 (VI9)</h1>
<p>

<h4>This scatterplot shows only the top 5 QBs, colored by rank, using a single-hue colormap.  I chose ColorBrewer's 5-class Blues color map.  For VI9, I have chosen to add a button to change the view to include all of the QBs, with the top 5 highlighted. </h4>
