All operations are done using a visual menu-driven interface. We drag and drop widgets that can have inputs and outputs. Widgets perform operations on data sent to them by other widgets. The visuals can be exported to PNG/SVG/PDF and the entire workflow can be exported into a Report Form and edited for presentation and sharing.

Orange also has add-ons that provide widgets for specific tasks such as Machine Learning, Time Series Analysis and so on.
