OrgOrgChart – the evolution of a company’s structure over time, visualized.



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
