One of the most important aspects of delivering a rich user experience is what a user sees and interacts with on the screen. Graphics, whether static or dynamic, comprise the face of an application. Static graphics can definitely suffice for creating the necessary visual parts of an application, but to change them you must replace them with other static graphics. Dynamic graphics, created with programmatic drawing are very powerful because it can be manipulated at run-time, but it can involve more advanced knowledge of the Drawing API. Degrafa is a declarative graphics framework that aims to offer the best of both worlds.

I've expanded upon the ideas of my last post: "Degrafa + Datagrids = Visual Display of Data", and I'm continuing to explore data visualizations using Degrafa. This time, I've decided to tackle the sparkline.

If you are a Flex developer, and you haven't checked out Degrafa yet, you should. Degrafa is an open source declarative graphics framework for Flex. It allows you to easily create complex shapes, patterns, skins, gradients, strokes, etc... without intimate knowledge of the drawing API. The framework allows you to do some really cool things, without a lot of code. Here's a quick example of what can be done with a Flex datagrid, Degrafa, and some time to kill.
