# Layers

## Types of Layers

### GeoJSON

GeoJSON layers can display either lines, polygons or points. For example, a lineGeoJSON layer can display data like road sections or trip routes. A polygon GeoJSON layer is essentially a [choropleth](https://en.wikipedia.org/wiki/Choropleth_map) layer and works best for rendering zone data. To add a GeoJSON layer, your dataset must contain geometry data.
