Inflace v datech: vizualizace vývoje spotřebního koše

This bachelor's thesis deals with the design, development, and implementation of an interactive dashboard focused on visualizing the development of consumer prices in the Czech Republic. The main motivation is to point out the diverse development of inflation in individual categories of the consumer basket and to show that monitoring only the aggregate figure is not sufficient. The theoretical part describes how inflation is measured using price indices (CPI and HICP), the purpose of the consumer basket according to the European ECOICOP classification, and the principles of effective visualization of economic data. The practical part is based on the definition of the target user and the processing of data from the Czech Statistical Office. The key section is the description of the dashboard's development in the Python programming language and the deployment of the application. In the dashboard itself, it is possible to analyze the weights of the consumer basket, the base index, the year-on-year index, the month-on-month index, and simulate the calculation of personal inflation. To verify the overall usability and comprehensibility of the dashboard, a questionnaire survey was conducted with target users. A part of the thesis is a graphical analysis of inflation trends in recent years as a demonstration of the dashboard's potential practical application. The resulting application serves as an educational tool for a better understanding of the different impacts of inflation on consumers with different spending structures.
