Using Degrafa for customizable data visualization

You have to see it to appreciate it. I especially like the capacity indicator “distribution ala itunes/ipod”, and the shape renderer. So sweet!

Degrafa & Data Visualization

While syncing in iTunes I was looking at the indication
of how my media was distributed across my iPhone and realized that same
visualization could be duplicated using Degrafa. I used a series of
different colored RegularRectangles, some VerticalLineRepeaters for the
inset markings that dynamically change count depending on the size,
some other Rectangles for highlights and shadows, and a
RoundedRectangle to mask the area. I also through in a ComplexFill
composed of a Solid, Bitmap and Blend fill to create the colored plaid
effect. This was really easy to do with binding to change the width,
capacity bars, inset marks and colors.
