The visible AI workflow demonstrates the agent autonomously reading the file and loading a data-visualization skill to process the request. The Live Preview pane instantly generated a comprehensive CRM Data Cleaning Results HTML dashboard, displaying a reduction from 320 initial contacts to 314 clean contacts. This dashboard highlighted the successful removal of 6 duplicates and the fixing of 46 invalid phone numbers, while simultaneously offering visual bar and pie charts for Deal Stage Distribution and Country Distribution.
