A visualization of letter-to-letter network data. This was created for the University of Illinois Coursera class on data visualization.
These data were obtained from the SCOWL (Spell Checker Oriented Word Lists) database, available here, http://wordlist.aspell.net. I generated a medium-sized database of English words, capital words, and abbreviations, and then computed the number of occurrences of letter #1 being succeeded by letter #2. The nodes are connected by chords, and the width of the chords represents the fraction of links from letter #1 that terminate on letter #2. The angle of the arc for each letter represents the fraction of all letters. Hovering the mouse on an arc highlights the links from that arc and fills the table with the letter-to-letter fractions. Hovering the mouse on a chord displays the letter-to-letter fractions.
