Greetings, Boost! I've been in the application process for Google's "Summer of Code", and John Maddock brought up the idea of rapid prototyping in order to start finalizing design ideas. Over a couple of days I worked out a rough sketch of how the user interface would be organized. The "Initial Proposal" below has a detailed description of what the project is about, but the rough idea is that I need to visualize data in STL containers using the SVG (Scalable Vector Graphics) format. The sample code provided uses std::vector<double> containers currently, and I will extend the idea to generic STL containers during the summer. Dr. Maddock had the idea that the class could use a stream-like interface, sampled below. svg_graph my_graph("file.svg"); my_graph<<x_scale(-10, 10)<<y_scale(-10, 10); my_graph<<plot_range(my_cont.begin(), my_cont.end()); I have the basic idea of streams working, but I haven't yet implemented multiple streams working in conjunction (as in line 2). Again, this is a rapid prototype that I squeezed in between schoolwork! I intend the main bulk of the work to be done during the summer, and I feel that I still need to do some refactoring of the code. I am looking for suggestions of directions people would like to see this project go. What would you like to customize in the output? Do you have a better idea for an interface? Am I taking the implementation in the wrong direction? How would you like invalid data to appear? Not at all? As a gray dot on an axis? I'd like to get a conversation going about what the user should/should not be able to do with this.
