The composite and complex data of the final mash-up dataset, we decided to use different types of graphs (pie, bar chart and line area chart) and to represent both the data concerning the fundamental theme of human trafficking; and data concerning the well-being of nations of the European Union.
Since the union of the datasets has allowed us to have a more comprehensive view on the data temporally speaking, we have chosen to represent the total number of victims for each country of the European Union (2003-2017). As regards the indicators of well-being and growth of a nation, we have chosen to represent the score for education and the net migration for each member State.
