Data visualisations are needed more than ever to understand the vast abundances of data that have surfaced. Visualisations can be used to convey the meaning behind the data. They can also be used as a method of data analysis. For long, data visualisations have been presented with two-dimensional media such as paper, chalkboards and computer monitors. As virtual reality technologies become more advanced and commercially available for the average consumers, visualisation can be brought into a whole new dimension of representation and interaction. The project was started based on the idea of building a data visualisation application that can be viewed through head-mounted displays and interacted with motion controllers. The application was constructed with Unreal Engine 4 game engine and the tools associated with it. During the development of the application, different features and data visualisation methods were evaluated and included in the final application when appropriate. The resulting application was a three-dimensional scatter plot visualiser that could be operated through a head-mounted display and motion controllers. With head-mounted displays, the users of the application could easily view the visualization from different perspectives. Motion controllers could be used to move, rotate and stretch the visualisation. The application supported visualising variables on four axes: three spatial dimensions and one colour axis. An implementation of t-SNE dimension reduction algorithm was also included in the application among other data analysis tools. Although the project finished successfully and the final result was functional, many ideas and feature requests from the assignors were left for future development. ; Datavisualisointia tarvitaan enemmän kuin koskaan ennen massiivisten tietomäärien ymmärtämisessä. Visualisoinneilla voidaan viestiä tiedon merkitys graafisessa muodossa. Niitä voidaan käyttää myös data-analyysin aputyökaluina. Datavisualisointi on perinteisessä merkityksessään ollut aina datan ...
