A vector tile layer references a set of web-accessible vector tiles and the corresponding style for how those tiles should be drawn. Vector tiles are similar to image tiles, but they store a vector representation of the data. Client-side drawing of vector tiles allows for vector tile layers to be customized for the purpose of the map, which drives dynamic, interactive cartography.
