## What it is
Muze is a free, composable data visualization library for the web that uses a layered Grammar of Graphics approach and WebAssembly for performance. It follows a data-first model with an in-browser DataModel, enabling interactive, multi-dimensional exploratory visualizations like Tableau.

## Use cases
- build interactive dashboards with cross-chart interactivity
- create exploratory data visualizations in the browser like Tableau
- render charts from large datasets with WebAssembly performance
- compose multi-layered charts using a grammar of graphics
- customize chart interactions and behaviors in a web app
- visualize transformed data with rich data operators

## When to choose
- you need highly interactive, composable charts driven directly by data transformations
- you want Tableau-style exploratory visual analytics embedded in a web application
- you need to visualize large datasets in-browser with WebAssembly-backed performance

## When to avoid
- you need a lightweight charting option for simple static charts
- you require a permissively licensed library - the WebAssembly version uses a custom license
- you need actively maintained software with recent releases and ongoing support

## Facets
- artifact type: library
- maturity: maintenance
- function: data-visualization, charts, wasm
- domain: data-visualization, frontend, web-development, analytics
- platform: browser
- tags: grammar-of-graphics, svg, interactive-charts, tableau-like, datamodel, visual-analytics, nodejs, javascript
