About Tool

Vizzy makes it easy to explore and present data without needing to code or use traditional BI tools. You upload data in JSON, CSV, XML, or similar formats, and ask Vizzy (via natural language) to generate visualizations. The tool infers the structure of your data and lets you refine its understanding by editing metadata before generating charts. Users can then request different types of visuals, change legends or color schemes, and even animate insights. Because it's powered by a large language model, Vizzy supports a conversational workflow you can ask for tweaks, explanations, or new visualizations as if you were talking to a teammate about the data.
