universal JavaFX/OpenJDK data science spreadsheet -- 3

It is a desktop application which could be described as a 'marriage between a graphics calculator and a spreadsheet' to assist students of data science projects. They load data into the internal SQLite database manually with DB Browser for SQLite or by writing custom Java code connectors that download data from the network. Then they use the data inside the internal SQLite database to create new results by writing custom Java code batch formulas. Afterwards they visualize all the data with 3D plots. You just have to provide a sustainable data-agnostic framework for years to come and do not need to know about all the details of data science.
