数据视频整合动态图表、语音叙述和同步动画,以时间叙事的方式传达数据洞察,使其成为提高数据管理生命周期中数据消费效率的有效媒介。然而,制作高质量的数据视频需要涵盖数据分析、叙事设计和视频制作的专业知识。现有方法存在不足:静态可视化工具(如BI仪表板)缺乏叙事逻辑和动画;创作工具要求用户预先准备可视化,而非从原始数据开始;像素级视频生成模型无法保证数据保真度或来源。我们演示了DataMagic,一个端到端的交互式系统,将原始表格数据和自然语言查询转化为叙事性数据洞察视频。为确保数据保真度,DataMagic引入了声明式规范DVSpec,通过数据驱动的语义引用将视觉和动画元素绑定到底层数据字段。为解决设计空间的组合爆炸问题,DataMagic采用先生成后编排的多智能体架构,并行生成候选场景,然后通过全局编排优化叙事连贯性。利用DVSpec逻辑与渲染的解耦,系统进一步支持三种交互模式和基于结构化来源的数据问答,将单向视频转化为可探索的交互式数据界面。在109个真实世界样本上的评估验证了DataMagic的有效性。主页:此 https URL
Data videos integrate dynamic charts, voice narration, and synchronized animations to communicate data insights as temporal narratives, making them an effective medium for improving data consumption efficiency in the data management lifecycle. However, producing high-quality data videos requires expertise spanning data analysis, narrative design, and video production. Existing approaches fall short: static visualization tools (e.g., BI dashboards) lack narrative logic and animation; authoring tools require users to pre-prepare visualizations rather than working from raw data; pixel-level video generation models cannot guarantee data fidelity or provenance. We demonstrate DataMagic, an end-to-end interactive system that transforms raw tabular data and natural language queries into narrative data-insight videos. To ensure data fidelity, DataMagic introduces the declarative specification DVSpec, which binds visual and animation elements to underlying data fields through data-driven semantic references. To address the combinatorial explosion of the design space, DataMagic adopts a Generate-then-Orchestrate multi-agent architecture that generates candidate scenes in parallel and then optimizes narrative coherence through global orchestration. Leveraging DVSpec's decoupling of logic and rendering, the system further supports three interaction modes and structured provenance-based data Q&A, transforming one-way videos into explorable interactive data interfaces. Evaluation on 109 real-world samples validates the effectiveness of the DataMagic. Homepage: https://datamagic-home.github.io/
