GeoJSON Track for HiGlass

Display your favorite GeoJSON annotation right in HiGlass.

Note: This is the source code for the GeoJSON track only! You might want to check out the following repositories as well:

• HiGlass viewer: https://github.com/hms-dbmi/higlass
• HiGlass server: https://github.com/hms-dbmi/higlass-server
• HiGlass docker: https://github.com/hms-dbmi/higlass-docker

HiGlass GeoJSON comes in 2 flavors, with and without including d3-geo in the bundle. The only difference is the file size:

• With d3-geo: 8KB minified and gzipped
• Without d3-geo: 2KB minified and gzipped

Installation

npm install higlass-geojson

2. Now, configure the track in your view config and be happy! Cheers 🎉
