Style layers

The Annotation API makes it unnecessary to write much of the code that would otherwise be required to implement runtime and data-driven styling. But, it is possible to add style layers directly, and in some circumstances doing so will be beneficial.

Benefits:

• Efficient and performant when adding many features to the map using a vector source.
• Also compatible with GeoJSON sources.
• Many style customization options.

Limitations:

• No default image available.
• User interactions are not built-in and will require writing custom code.
• Need to learn the APIs and usage of layers which can be time intensive.
• Might need to learn how to use expressions to control the source data or use data-driven styling.
