11000 emails per day, 2000 people.
This artwork shows 1 day of email exchanges between all employees of a Swiss company and the outside world where each dot is either an employee or an external correspondant. Colored by business units, we can clearly see that the flow of information is well distributed across the different branches.
I also had the chance of making an interactive version of this piece using WebGL. As you can see in the video, or live in your browser (Desktop version - Google Chrome preferred), you can filter by anonymized business unit, change the speed - play, pause and change different color settings from the sidebar.
It is a massive challenge to load that amount of data the web and display everything at once, we've used several coding tricks and custom shaders to make it work.
