Visual Workflow Example — Orange Code
An example showing a simple workflow in Orange for classification or clustering using the visual interface.
// In Orange Canvas:
// 1. Add 'File' widget to load dataset
// 2. Add 'Data Table' or 'Scatter Plot' for visualization
// 3. Add 'Test & Score' or 'Classification Tree' for modeling
// 4. Connect widgets to build the workflow interactively
// Python scripting can extend the workflow for advanced tasks.Orange Language Guide
