This Web application visually displays the randomness in two Croatian lottery systems: the 6/45 and 7/39 system. The goal of the application is to visually explore the degree of uniformity of the drawn numbers. The application uses data made publicly available by the Croatian lottery here (for 7/39) and here (for 6/45).
The application is developed by Ivan Zuzak and is available under the Apache 2.0 License. I have no claim over the data provided by the Croatian lottery. For more information and the source code of the application, visit the GitHub repository.
