Electoral interactives

How the Congress would be different whether the law was changed?

The Spanish electoral system distributes a total number of 350 seats. Votes are agregated by constituency and seats are assigned taking into account the D’Hondt method, excluding the parties with a share of votes by constituency under a specific threshold. Current law assings the constituency to be the province and 3% as the threshold.

Out team has conceptualized, designed and developed an interative to learn how how the Congress would be different whether the law was changed.


The main goal was to design an easy interaction for an user without previous knowledge to be able to understand the effects that certain parameters such as constituencies or vote threshold have in the law. CARTO has been the platform of choosing to store and process data. To build an interactive that could adapt to different screen sizes we have been using HTML5 y JavaScript libraries such as Bootstrap or D3.
