using SpringGraph for any flex project:
SpringGraph is a 2D data visualization API based on the flex 2. I have used flex 3 sdk to demo the example of spring graph.
first of all, a package should be downloaded for using SpringGraph at developer blog. Extracting the package, copy ./SpringGraph/bin/SpringGraph.swc to the directory named simple.
The package provides five examples for testing SpringGraph. going into simple SpringGraphDemo. using command to compile the mxml file, like:
mxmlc -library-path+=../SpringGraph.swc SpringGraphDemo.mxml
than using a flash player open SpringGraphDemo.swf. the interface should like this example.
