Vector layers are extremely useful for developing interactive web mapping applications. In this chapter, we've discussed what a vector layer is and its potential limitations. We've explored the various vector data sources that OpenLayers provides, and looked in detail at features and geometries. Through a series of examples, we learned how to load dynamic data from a remote server such as a WFS server, load tiled vector data, load vector data stored in static files, even by dragging them to the map from our file browser, work with geometries and features, and dynamically interact with vector data.

We covered a lot about vector layers, but we're not done yet. It's time to take control of the presentation of our vector data; so, keep reading to learn all about how to use styles with vector layers to really make your maps pop!
