In 2013, the information designers Giorgia Lupi (living in New York City) and Stefanie Posavec (living in London) began a year-long project to get to know each other through hand-drawn data-centric postcards. Each weekly postcard communicated a different aspect of their lives through data visualisation, from the frequency they checked the time of day to the number of times their significant others ‘inspired love or inspired annoyance’. A brief but enlightening summary of Giorgia and Stefanie’s experience, Dear Data illuminates the potential (and shortcomings) of data-driven communication and suggests how visualisation can imbue even the most seemingly tedious facts and figures with emotion. See all of Giorgia and Stefanie’s postcards here.
