VisCanvas: A Node-based Interface for Exploratory Visualization Authoring with LLMs

Researchers introduced VisCanvas, a node-based LLM interface for creating and iterating on visualizations in a non-linear workflow.

The system supports revision, branching, and merging, aiming to make exploratory data analysis more flexible than chat-only tools.

In a study with 20 participants, VisCanvas enabled broader exploration of data while showing similar cognitive load and usability to a chat-based interface.

The results suggest node-based interaction may better support AI-assisted visualization authoring and inform future tool design.
