How to use Orange for data analysis and visualization
Once you have downloaded and installed Orange, you can start using it for data analysis and visualization. Orange has a graphical user interface that allows you to create data analysis workflows visually, with a large, diverse toolbox of machine learning and data visualization techniques. Here are some of the main features of Orange that you can use for data analysis and visualization:
Visual programming
Orange uses a visual programming approach that lets you build data analysis workflows by dragging and dropping widgets on the canvas and connecting them with wires. Widgets are small components that perform specific tasks, such as loading data, preprocessing data, applying machine learning algorithms, plotting data, etc. You can find widgets in different categories on the left panel of the Orange window, such as Data, Visualize, Model, Evaluate, etc. You can also search for widgets by name or keyword using the search box on the top left corner of the window.
