Aim :Visual Programming with Orange Tool, What is visual programming

Orange Tool:

Orange is a component-based visual programming software package for data visualization, machine learning, data mining, and data analysis.

Orange components are called widgets and they range from simple data visualization, subset selection, and pre-processing to empirical evaluation of learning algorithms and predictive modeling.Visual programming is implemented through an interface in which workflows are created by linking predefined or user-designed widgets, while advanced users can use Orange as a Python library for data manipulation and widget alteration.

 

What is Visual Programming?

Visual programming is a form of programming language that uses illustration to allow humans to represent processes. It is a technique that was made to work with our ability to explain concepts through visual means. The inclusion of graphical elements makes it accessible to new learners. These elements can be manipulated to construct programs.
