To do this, he extracted the correspondence history from November 1, 2012 to September 1, 2014. It contained 3000 messages. Based on the data, he created a Gantt chart to decide which passage from the conversation was best suited for visualization. For example, he wanted the infographic to have a punch line. Pütz did most of the work in Processing.
He divided the extracted messages into four groups: regular, with a link to YouTube, with a smiling emoticon, and with a question. In the infographic they are shown in white, red, yellow and blue colors, respectively. Concentric circles and waves that radiate from the two circles indicate the length of messages received.
