Abstract [en]

Complex data are being stored daily in databases in an unstructured way. Visualizations techniques can be used to present complex data in a user friendly and understandable way. This thesis presents the implementation of a visualization interactive tool called Eco Donuts. It is part of a set of tools created to visualize complex food data called Ekopanelen. The feature Eco Donuts presents time-dependent food data which are ordered in categories. It gives the opportunity to users to explore their data over time by performing simple interactions. This thesis documents an exploratory study on how this visualization tool can be used to enhance the user experience and provide insights of complex data. The visualization feature was implemented and evaluated with ten participants. The participants were asked to evaluate the visualization tool by accomplishing nine different tasks. The sessions were recorded using a log system as well as video recording. This study shows that the proposed tool can be used to visualize complex information in a user friendly and presentable way.
