This bachelor thesis focuses on exploring the field of data visualization and its ability to facilitate data analysis through the creation of appropriate visualizations. The aim of the bachelor thesis is to describe the topic and possibilities of data visualization, the visualization tool used for creating visualizations in the practical part, select datasets and design its’ visualizations. The bachelor thesis is structured into two main parts: theoretical and practical. The theoretical part introduces the field of data visualization, including historical development, classification, basic principles, and current trends in the field. This part also compares the most significant tools for data visualization and justifies the choice of the Qlik Sense tool, which is used in the visualization processing. The practical part of the thesis focuses on the process of selecting datasets for a specific company, subsequent visualization design, and evaluation. Ultimately, a dataset for the specific company was selected, which already contained existing visualizations available on its web portal. Three modified visualizations were proposed as inspirational examples for future modifications of existing graph. Subsequently, a questionnaire survey was conducted among independent experts in the field and a brief interview with the main statistician of the chosen company to evaluate the created visualizations. The main contribution of this bachelor thesis is the presentation of new visualization variants that offer expanded and useful technical possibilities. These variants can serve as examples for future development of existing visualizations for better data presentation and analysis.
