VizGPT is a contextual data visualization chat interface that uses natural language to generate visualizations from datasets. It allows users to edit the visualization in context step-by-step, without retyping complex queries. Traditional drag-and-drop visualization tools can be hard for people unfamiliar with data transformations and configurations, while some text2viz tools lack flexibility when it comes to editing visualizations. With VizGPT, users can build visualizations through a chat interface and explore their data first before figuring out how to create complex visuals. The tool currently focuses on drawing data visualizations rather than transformations/preparation/computation.
