Exploratory data visualization built in the context of the BBVA Innova Big Data Challenge contest. BBVA is the first bank in Spain to hold an international developer competition, inviting developers to build new services, applications and contents based on its card transaction data.


This visualization, which received and honorable mention due to its innovative approach, reflects consumption flows and distances traveled ​​by different types of BBVA customer from their place of origin to the point of purchase. To this end, this visualization uses all the information from the API created by BBVA for Innova Challenge, while combining this with external sources such as Google Maps, CartoBCN (Barcelona City Council) and the National Center for Geographic Information. The result is spectacular graphics on a 3D map of the city of Madrid and Barcelona.


Revealing mobility
