In the previous chapter we looked at the basics of graph drawing. We investigated the different ActionScript features that allow us to draw graphs of various shapes and sizes. We also looked at how to structure the data to easily create graphical representations.

In this chapter, we are going to investigate how to get that data into your program. Various sources will be discussed. These range from plain files to remote web services.

The final recipes discuss the opposite, extracting the data from your application into a format that other programs can use.
