SandDance is a data visualization tool developed by Microsoft Research’s VIDA Group, aimed at helping users visually explore and understand their data. It employs unit visualizations, which directly map database rows to visual elements on the screen. This approach makes it easier to discover insights, test hypotheses, and support decision-making. The tool features smooth animations that maintain context during data interactions, making it user-friendly for both casual and serious analysts. The latest iteration of SandDance has been completely rebuilt for modularity and extensibility, allowing integration into various applications. It is available as an open-source project on GitHub, inviting community contributions and discussions. The core components include a visualization canvas, React-specific versions, and options for embedding in other applications. SandDance uses libraries like Vega for chart layouts, enhancing its capabilities. Key updates include a significant version bump to v4 in July 2022, which introduced MorphCharts, and earlier updates that incorporated advanced technologies like Deck.gl and Vega. The project requires contributors to agree to a Contributor License Agreement (CLA) and adheres to a Code of Conduct. For those interested in data visualization, SandDance provides a robust platform for turning data into actionable insights.
