From the developer:
PlotDevice is a Mac application that lets you write Python scripts to generate 2D graphics using simple drawing commands. Under the hood, your code drives the system's Quartz imaging engine, giving your scripts the same graphical power as a full-fledged Cocoa app.
Your code can combine basic geometric shapes, typography, free-form Bézier curves, and a panoply of image formats.
You may want to check out more software for Mac, such as ChIDE, EcoLab or flex sdk 3, which might be similar to PlotDevice.
