City of Montreal
Contracts Portal

The Contracts Portal was developed as a research project for the City of Montreal, to enable citizens to understand where the city’s money goes and how the money is distributed. 
FFunction proposed a treemap structure for exploring the contracts, giving users the ability to easily see patterns that would be difficult to spot in other modes of representation. A second advantage of treemaps is that they make efficient use of space. As a result, they can legibly display hundreds of items on the screen simultaneously. This is ideal for mapping a whole contracting landscape, allowing citizens to search for the most costly contracts and largest suppliers of the City. Users have many filter options to sort and view the data, allowing for a high degree of flexibility in how the material is presented.
