Organic organization chart (video)

The OrgOrgChart (Organic Organization Chart) project looks at the evolution of a company's structure over time. A snapshot of the Autodesk organizational hierarchy was taken each day between May 2007 and June 2011, a span of 1498 days. Each day the entire hierarchy of the company is constructed as a tree with each employee represented by a circle, and a line connecting each employee with his or her manager. Larger circles represent managers with more employees working under them. The tree is then laid out using a force-directed layout algorithm.

From day to day, there are three types of changes that are possible:

  • Employees join the company
  • Employees leave the company
  • Employees change managers
Instead of recomputing the full layout each day, we animate the transitions from one day to the next. In this version of the video, each second corresponds to approximately 1 week of activity.
