### geometryStyles?

> `optional` **geometryStyles**: { `Point`: `object`; `Line`: `object`; `Polygon`: `object`; }

The styles to apply to each geometry on the layer.

Each style should be a valid FSL style, as described in [Layer.style](https://developers.felt.com/js-sdk-api-reference/layercommon#style).

These are optional, and if missing will use a default style determined by\
