This anonymous designer visualized the data from their concurrent capture activity using hue and size. The postcard reads from bottom to top, left to right. The colors of the coffee beans correspond to four different coffee-making activities, and the size of each coffee bean represents how long it took to do that particular activity at that time. Tiny beans represent 15-30 seconds, and big beans are multiples of the tiny beans. See the back of the postcard for the key and other details!
