GenomeSpy is a visualization toolkit for genomic (and other) data. It has a Vega-Lite inspired visualization grammar and a high-performance, WebGL-powered graphics renderer.

The software is still work in progress. Documentation and examples for the current version can be found at https://genomespy.app/

GenomeSpy is split into several packages, two (core and app) of which are the most important:

The core library provides the visualization grammar and a WebGL-powered rendering engine.

The app builds upon the core, extending the visualization grammar with support for faceting multiple (up to thousands of) patient samples. It provides a user interface for interactive analysis of the samples, which can be filtered, sorted, and grouped flexibly. A session handling with provenance, url hashes, and bookmarks is included.

The embed-examples package contains examples of how to embed GenomeSpy in web applications and use the API for advanced use cases.

1. git clone [email protected]:genome-spy/genome-spy.git
2. cd genome-spy
3. npm install (use npm7!)
4. npm start (starts a development server with the app package)

The packages/core/examples directory contains some random view specification that can be accessed through urls like http://localhost:8080/?spec=examples/first.json.

The packages/core/private/ directory is in .gitignore and served by the development server: http://localhost:8080/?spec=private/foo.json. Use it for experiments that should not go into version control.

If you want to use or develop the core library, launch a single-page app using: npm -w @genome-spy/core run dev
