Adobe Flex
Builder was
recently changed
to Adobe Flash
Builder. There are
small differences
between the two,
but you can use
either.

As in Chapter 5, “Visualizing Proportions,” when you create a stacked
area chart with ActionScript and the Flare visualization toolkit, I highly
recommend you use Adobe Flex Builder. It makes ActionScript a lot easier
and keeps your code organized. You can of course still code everything in
a standard text editor, but Flex Builder wraps up the editor, debugging,
and compiling into one package. This example assumes you do have Flex
Builder, but you are of course welcome to grab an ActionScript 3 compiler
from the Adobe site.

To begin, open Flex Builder 3, and right-click the left sidebar, which shows
the current list of projects. Select Import, as shown in Figure 8-36.
