DataMagic: Transforming Tabular Data into Data Insight Video

DataMagic is an end-to-end interactive system designed to convert raw tabular data and natural language queries into narrative data-insight videos, addressing the limitations of existing visualization tools. It introduces the declarative specification DVSpec to ensure data fidelity by linking visual elements to data fields and employs a Generate-then-Orchestrate multi-agent architecture for efficient scene generation and narrative coherence optimization. This system enhances data consumption by providing three interaction modes and structured provenance-based data Q&A, making it a valuable tool for practitioners aiming to create dynamic data narratives.
