Graphs for Site Design

After scraping data for the site, I made the graphs for the header, icon, and background.  The header compares the letter frequencies from the Data Science Wikipedia article and overall letter frequencies.  The icon is the same data, but only using the letters for ‘Tyler’.  The header and icon plots were make with ggplot2, while the background used base graphics.  Tricky aspects include just getting the plot from ggplot2 and making a transparent background for the icon.
