Frequently Asked Questions
Do I need to train Q&A?
Q&A works automatically based on your data model. Adding synonyms and phrasings improves accuracy but is not required. The more business-friendly your column names, the better Q&A works out of the box.
Can Q&A work with all visualizations?
Q&A can create most common visualization types including bar charts, line charts, tables, cards, and maps. For complex custom visuals, users may need to use the standard report interface.
