Lexigraphs I is the first visualization from the Data Portraits series. Micro-blog authors use mobile text messaging or web interfaces to post short answers to the question What are you doing?, creating a stream-of-consciousness account of their daily encounters, musings, plans and actions. Using salient words from an individual’s postings, we visualize the topical and temporal patterns to create a portrait of the author.

The words on the left side of the silhouette show the daily rhythm (one day is two seconds) while the right side shows a cumulative view.
