In this chapter, we have covered in detail what constitutes real-time data and how to visualize and get the latest features. We will be dealing with how to deal with time-aware layers and how to visualize spatio-temporal layers in later chapters. Thus, we will be able to build effective web applications that are refreshed continuously. In the following chapters, we will be dealing with advanced visualization techniques using the statistical capabilities of the feature layer, and learning about charting libraries.
