Stamen Design has started a project called 'Beatquake' . This is the coloured graphs which are overlapped on each other and height of each graph shows the popularity. It maps the volume of listens for each of the top three most popular songs in the U.S. each day over a period of 90 days.
You can find more information in Facebook Stories. For detailed knowledge on how this works, visit Stamen Design page.
