The Tour de France cycling stage race is the largest sporting event in the world organized annually. From its creation in 1903 to 2023, 110 editions were held. Due to their spatial variability, which is represented by individual stage places and mountain climbs, they are also extremely interesting from the point of view of geography as a spatial science. In a longterm history, we have identified a total of 756 stage places and 342 mountain climbs of the second, first category and so-called "Hors catégorie". Using the example of collected historical data stored in a database, we point out the main trends in its development from the point of view of the representation of stage finish places and mountain climbs in individual decades. Here we observe a clear trend from the inclusion of stable stage centres in the itinerary of individual editions, to the increasingly frequent inclusion of new stage centres with less periodicity of inclusion in the stage itinerary. A similar trend is also visible in mountain climbs. Here, however, in addition to the discovery of new climbs, we can also see the regular inclusion of some today "iconic" climbs that have their irreplaceable place in the Tour de France history (Tourmalet, Aspin, Galibier, Alpe d'Huez, etc.). The contribution also includes a website (www.aguc.tdfrance.eu) where client can create his own map outputs of stage finish places and mountain climbs for any period. These maps are created by using the D3 digital library, the TopoJSON format and the MySQL database system. It also includes a comprehensive data visualization of selected historical statistics created in the PowerBI program. This allows researchers, who are not familiar with any programming language, to visualize and subsequently share data on the Internet. We consider data visualization to be an extremely important part of (not only) geographical research, because of sharing research results on the Internet in an at - tractive form is an important tool for promoting geography as a scientific discipline.
