## What it is
SandDance is a JavaScript data visualization library from Microsoft Research that creates unit visualizations with a one-to-one mapping between data rows and on-screen marks, featuring smooth animated transitions between views. It ships as modular React-friendly components and is also available as a web app, Power BI visual, and VS Code/Azure Data Studio extensions.

## Use cases
- visually explore a csv dataset in the browser
- embed an interactive data explorer in my react app
- animate between chart views while keeping context
- present data stories with unit visualizations
- add a visualization canvas to a power bi report
- let users filter and facet data without writing chart code

## When to choose
- you want animated unit visualizations where each row is a mark
- you need an embeddable explorer UI in a React or JavaScript app
- you want a no-code data exploration view for non-technical users

## When to avoid
- you need standard aggregate charts like simple bar or line charts with minimal bundle size
- you need server-side rendering or static image export of charts
- your data is too large to render one mark per row

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, charts
- domain: data-visualization, data-science, web-development
- platform: browser, cross-platform
- tags: unit-visualizations, vega, deck-gl, react, powerbi, microsoft-research, typescript, embeddable, web-server, nodejs
