Introduction

This chapter delves into the additional JavaScript libraries that are part of the Google Maps JavaScript API. These libraries are not added to your application by default when you reference the Google Maps API; however, these can be added manually.

These libraries are classified into the following six categories:

• drawing
• geometry
• places
• panoramio
• visualization
• weather

The last three libraries in the preceding list—panoramio, visualization, and weather—have been discussed thoroughly in Chapter 2, Adding Raster Layers, with respect to their related topics and usages. In this chapter, we will learn in detail about Drawing and Geometry libraries. We will also use two external libraries.

The intention of these libraries, as extensions to the core API, is to ensure that the Google Maps JavaScript API is self-sufficient in order to provide all of the tasks that it offers to accomplish. That means, without these extra libraries, you can develop using the API without any problem...
