Vega-Lite Ecosystem

This is an incomplete list of integrations, applications, and extensions of the Vega-Lite language and compiler. If you want to add a tool or library, edit this file and send us a pull request.

We mark featured plugins and tools with a .

Tools for Authoring Vega-Lite Visualizations

  • Vega-Editor, the online editor for Vega and Vega-Lite. You can also get an output Vega spec from a given Vega-Lite spec as well.
  • Vega Viewer, a VSCode extension for interactive preview of Vega and Vega-Lite maps and graphs.
  • vega-desktop, a desktop app that lets you open .vg.json and .vl.json to see visualizations just like you open image files with an image viewer. This is useful for creating visualizations with Vega/Vega-Lite locally.
  • Voyager (2), visualization tool for exploratory data analysis that blends a Tableau-style specification interface (formerly Polestar) with chart recommendations (formerly the Voyager visualization browser) and generates Vega-Lite visualizations.
  • Chart Builder, a chart builder that imports data from queries in The generated specs can be saved locally or uploaded back to Project is open source.
  • ColorBrewer-Lite, a fork of the ColorBrewer project that allows importing Vega-Lite specifications into the ColorBrewer interface to pick effective color schemes “in situ” for any color encoding.

Plug-ins for Vega-Lite

Bindings for Programming Languages

  • Altair exposes a Python API for building statistical visualizations that follows Vega-Lite syntax.
  • Elm-Vega generates Vega-Lite specifications in the pure functional language Elm.
  • Altair wrapper in R

Programming / Data Science Environment that supports Vega-Lite

  • JupyterLab, an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook and Architecture.
  • nteract, interactive notebook application with Vega and Vega-Lite renderer.
  • Observable, an interactive JavaScript notebook. Embed example and exploration example.
  •, upload .vg.json and .vl.json files along side your raw data, or embed Vega directly into comments and summary markdown.
  • nextjournal, scientific computing environment with support for data visualizations including Vega-Lite
  • Liminoid, toolkit for building interactive analytics applications with Python and WebAssembly. Can pass Python data to JavaScript callbacks which render Vega/Vega-Lite specifications.

Tools that use Vega-Lite

  • Lyra, an interactive, graphical Visualization Design Environment (VDE)
  • Saite Interactive exploratory graphics and ad hoc visualization application for Clojure(Script). Built on top of Hanami.
  • PdVega, lets you create interactive Vega-Lite plots for Pandas. Uses ipyvega.
  • Turi Create Apple’s tool to simplify the development of custom machine learning models.
  • mondrian-rest-ui, an experimental UI for mondrian-rest inspired by Polestar and CubesViewer.
  • Django Chartflo, charts for the lazy ones in Django
  • Vega-Lite for PowerBI is an example of a PowerBI custom visual built with Vega-Lite.
  • Sci-Hub stats browser provides coverage and usage statistics for Sci-Hub.
  • Iris, a conversational agent for data science.
  • dashcard: a simple Bootstrap-based UI for dynamic dashboarding using Vega-Lite and Mondrian via a REST API.
  • histbook, a versatile, high-performance histogram toolkit for Numpy.
  • Olmsted: a web application for biologists to explore and visualize the adapative immune system using deep sequenced B-cell receptor data. The app uses Vega’s interactive capabilities in the context of a React/Redux application to allow users to drill down into the data at multiple levels of granularity, and is currently being used by HIV researchers in the quest for a vaccine. Demo available here.
  • Provides free search and analysis for millions of patents and scholarly works. Simplified interface for creating Vega-Lite data visualisations.
