title: Plotting engine
body: <p>in the C/C++ Area i don't know a light weighted and nice looking library for creating graphs.
  I am interested in creating a C++ library with the "gnuplot" functionality as a long term project - first with drawing lines :) .</p>
  
  <p>For this reason i am interested in Papers, keywords, structure and so on where to take look at.</p>
  
  <p>In the first step it would be enough to create one image format like <em>Jpeg or PNG, EPS</em> <strong>without using a window</strong> to draw on.</p>
  
  <p>Hopefully i will get information’s where to look :)</p>
  
  <p>Greetings</p>
