Take a look at 317 by Carolina Andreoli. According to Carolina:
“317 is an exploration of how emotionally close versus how geographically close the people I have met in my life are to me. Each ring represents a person, and each colour represents the countries where I’ve met them. The rings on the left are the people who are emotionally closest to me, and to the right are the ones less close. The ‘staying in touch’ graph reveals how often I communicate with each person, whether face-to-face, phone, email or Facebook. The timeline at the bottom, not only links each colour to its country, but also shows when I lived in these countries, allowing the viewer to put all the information together.”
