Visualizing the Heartbeat of Twilio

Voxlineas is a live visualization of phone calls being made on Twilio, showcasing the heartbeat of the platform by displaying anonymized views of call routing in context. The initial design featured blue raindrop-like lines that were later adjusted to improve visibility, with subsequent changes including color, speed, and duration iterations to optimize the visual representation for longer calls and varying lighting conditions. Through a combination of paper sketches, sample data prototypes, and iterative development, Voxlineas was refined to utilize HTML, CSS, and Processing, allowing it to run seamlessly in Chrome on a large screen. The visualization was successfully showcased at Twilicon 2012, with plans to host it in the Twilio office moving forward.
