What file formats does Vizzy support?

Vizzy primarily supports CSV and standard structured data files that can be processed via DuckDB.

Is Vizzy open source?

Yes, Vizzy is an open-source project, and users are encouraged to contribute to its development on GitHub.

What is the success rate of the AI in creating charts?

According to project documentation, it maintains a high success rate (reported around 77% to 96% depending on the version and retry passes) for converting natural language to accurate SQL.
