7. The system of claim 1 , wherein the visualization generation engine is configured to:

determine, based on the collaboration graph, that a user is over-utilized; and

insert an icon into a visualization that indicates the over-utilized user.

8. The system of claim 7 , wherein determining that a user is over-utilized includes:

counting a length of time of all tasks assigned to the user; and

determining that the length of time is greater than a threshold amount.

9. The system of claim 1 , further comprising:

a front-end interface engine configured to provide a set of user interfaces to the sheets; wherein the set of user interfaces includes one or more of:

a sheet management interface; and

an email sharing interface.

10. The system of claim 9 , further comprising a plurality of computing devices configured to access the set of user interfaces provided by the front-end interface engine, wherein the plurality of computing devices include one or more of a desktop computing device, a smartphone computing device, a tablet computing device, and a laptop computing device.

12. A method of automatically provisioning new sheets in a collaboration system to match existing sheets, the method comprising:

collecting, by a computing device, interaction information representing interactions between a plurality of users and a plurality of sheets stored in a sheet data store;

generating, by a computing device, a collaboration graph that represents relationships between the sheets and the users;

calculating, by a computing device, similarities between the sheets based in part on the relationships between the sheets and the users;

determining, by a computing device, one or more discrepancies within sheets determined to be similar; and

updating, by a computing device, the sheets determined to be similar to eliminate the discrepancies.

13. The method of claim 12 , wherein calculating similarities between the sheets includes analyzing sheet metadata information that indicates relationships between the sheets along with the interaction information using a clustering algorithm.

collecting, by a computing device, interaction information representing interactions between a plurality of users and a plurality of sheets;

generating, by a computing device, a collaboration graph that represents relationships between the sheets and the users;

updating, by a computing device, the collaboration graph with information regarding similarities between vertices; and

generating, by a computing device, a visualization based on the updated collaboration graph that illustrates relationships between sheets and relationships between users.

16. The method of claim 15 , wherein generating the visualization includes:

presenting a set of sheet icons representing the plurality of sheets, wherein the set of sheet icons are arranged according to similarity groups.

17. The method of claim 16 , wherein generating the visualization further includes presenting at least one connection from a user icon to one or more sheet icons to represent interactions between the user and the sheets.
