Hi. Let's say there is a need to recreate a primitive plot like http://img27.imageshack.us/img27/6001/graz.png [Broken] Surely I can Photoshop it, I can even generate it using Mathcad or such, but pictures look awkward when imported into documents... I dare to say I want them scalable and pretty. Would "Microsoft Visio 2010" be decent for this? Other suggestions? What Google query should I use to get some examples?
