An Introduction to GraphViz
Using dot, twopi and NEATO to create graphics is not difficult. The three utilities were made according to the UNIX philosophy: they are easy to use, they do one thing well and the only requirement for using them is a simple text editor.
Graphical tools that make use of dot, twopi and NEATO languages for making graphs exist as well, but I still prefer the command line. The presented tools can be used for simple graphs as well as for complex graphs.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
