The aim of this Master's thesis is to explain geovisualization through theory to a practical example. Geinformation systems and geovisualization are explained as a term, as well as their history, their components and use. In the thesis is also explained the importance of the programming language Pythone, especially in geovisualization, and several examples are given to understand their connectivity. The topic was handled independently with the help of the literature and various web sources. To make geovisualization even clearer, a hands-on project called „Geovisualization of hotel accommodations on the Croatian coast was developed, showing hotels on the DOF map with some additional information such as address, city, telephone number, sead distance, number of floors and class. With each data, its coordinates were also found separately to allow it to be displayed on the map. Design and editing of the data presentation were also used to make the data as visible and organized as possible on the map. After the completed project, a statistical analysis was conducted on the requested data such as the city with the largest number of hotels, the total number of 5 star hotels, the total number of hotels whose distance from the sea is more than 1000 m, etc. It was found that the Croatian coast is rich in hotels, this figure it is growing year by year, and that more and more is being invested in tourism in general.
