Like the hip-hop visualization, Evolved uses a scrolling timeline to cover 60 years of hits. A sample from a song plays for as long as it held down the number one slot on the Billboard chart.

The timeline charts Billboard's hip hop singles chart from 1989 to 2015. The core of the visualization is a side scrolling timeline that slides through a month in about 12 seconds.
