# Module: ext/lz-forest-track

Forest plot track, designed for use with PheWAS style datasets. This is not part of the core LocusZoom library, but can be included as a standalone file.

### Features provided

- module:LocusZoom_DataLayers~forest
- module:LocusZoom_DataLayers~category_forest

### Loading and usage

The page must incorporate and load all libraries before this file can be used, including:

- LocusZoom

To use in an environment without special JS build tooling, simply load the extension file as JS from a CDN (after any dependencies):

    <script src="https://cdn.jsdelivr.net/npm/locuszoom@INSERT_VERSION_HERE/dist/ext/lz-forest-track.min.js" type="application/javascript"></script>

To use with ES6 modules, the plugin must be loaded and registered explicitly before use:

    import LocusZoom from 'locuszoom';
    import ForestTrack from 'locuszoom/esm/ext/lz-forest-track';
    LocusZoom.use(ForestTrack);

Then use the layouts made available by this extension. (see demos and documentation for guidance)
