DeepVIS enables transparent and interactively steerable data visualization from natural language queries by employing a five-stage Chain-of-Thought reasoning process. This approach, which fine-tunes a small-scale LLM on an augmented dataset, achieves state-of-the-art 77.16% overall accuracy in NL2VIS, outperforming larger general-purpose LLMs while improving user comprehension and refinement efficiency.

Key insights

  • Decomposing the NL2VIS task into a structured, step-wise Chain-of-Thought reasoning process substantially enhances LLM performance and output transparency.
  • Augmenting LLM inputs with database schema descriptions and value sampling is critical for accurate data retrieval and conditional logic in visualization generation.
  • Interactive interfaces that expose and allow refinement of intermediate reasoning steps significantly improve a user's ability to identify errors and efficiently steer the AI's output.
