Now that we know how to draw graphs, it's time to look at one of ActionScript's strengths: interacting with the user. In this chapter, we'll see many ways you can give the user control over the graph.
You will notice that this is only a starting point. There are so many options and so many ways to interact with a graph, it would be impossible to describe them all. An application such as Google Maps demonstrates many of the different ways:
Drag the graph to show parts that are not displayed
Zoom in and out to show details or the overview
Hover over markers to show more information
Click and select markers to perform actions
Display different versions of the same data (also called overlays in many applications)
With the recipes in this chapter, we want to give you a great start and encourage you to experiment.
