Larger State-Transition Diagram

In the blog, you will see that the state-transition diagram is much larger than it needs to be.  

I was able to find an SVG file of that diagram which allows me to make significant adjustments to it.  The nice thing about an SVG is that it's a text file that describes vector graphics.  This allows you to expand a graphic as large as you want.  I did not need the entire state-transition diagram.  I only needed the operational zone.

I modified the original SVG so that it only displays the operational zone of the freeze dryer.  This makes much better use of the screen real estate.  I was able to make the operational zone about 4 times larger than the original diagram that used a PNG.
