The European parliament has in the year of 2013 defined a set of changes to the 2003 directive that defined a set of rules for re-usage of information of public sectors. It is stated, that documents created by the state's officials represent a valuable resource of knowledge for the economy\cite{direktiva}. Following that directive, the Republic of Slovenia is providing access to its open data on the states websites. While the data was interesting and useful, it lacked the means to make it easier to understand and compare. That is why we decided to make an application that would cover that area. Application, while using the data provided and numerous filters set by the user, can draw graphs and by doing so, help visualize the data. The user can freely decide the number of municipalities and filters to use. After doing so, the application will use the set filters and its programmed logic to decide how to best portray the data. To make the application we used a so-called MEAN stack, which, in short, stands for technologies MongoDB, Express, AngularJS, and Node.js. The technologies were adapted to needs and trends, and the final selection was made by dropping Express, updating AngularJS to Angular2 and swapping JavaScrpit with Typescript.
