Every day, Jen Lowe renders a visualization with the most intimate of personal data—her heartbeat. She records her pulse with the Basis health-tracking wristwatch, then once a day uploads the information to onehumanheartbeat.com to replicate her heart, albeit on a 24-hour delay. The project is part of a larger trend toward live-updating visualizations that change in real time. A throbbing red light at the center shows her heartbeat. The outer ring counts down her (expected) days remaining on Earth.
