The speech comparison data visualization is a sketch built in Processing. It parses words from 9 famous speeches and displays the results in a custom diagram. All words are arranged in the right-hand side, ordered by the number of times they appear in the speeches. Each word has an arc divided into 9 colors representing the speakers. By looking at these arcs, you can see the word-use percentages of all speakers.
By pressing keys 1-9 you can highlight a single speech to get an overview of the word-use. Pressing the number 0 will show all the speeches again. Pressing space will reset the sketch and show the arc animation from the beginning.
