A Lightweight Visual Programming tool for Machine Learning and Data Manipulation

In recent decades, visual programming tools have focused on scientific workflow tasks. However, the current focus has shifted to machine learning tasks, which are most often amenable to unification. The existing solutions in this area demonstrate many alternatives with the possibility of using models from various machine learning packages. The proposed solution is based on the concept of minimal graphical notation, where all typical operations on data and machine learning models are possible. Another distinguishing feature of the proposed solution is the explicit separation of data and models, making the proposed notation clearer for perception. In the proposed engine, computational graph traversal does not have a rigorous sequence. The call of the sequence of calculations depends on the specific model that the user currently needs.
