This is a tricky question, number of component in a graph has nothing to do with the level of knowledge a person has. On the contrary, a proper standardized and modular parametric approach will reduce the number of components to a very few. In a well thought modular and parametric design, mostly the graphs will have 3/4 components, which will be doing a particular task and will then call another sets of graphs to do the next and so on. This way total numbers of distinct graphs will drastically come down, support and maintenance will be much more simplified. The bottomline is, there are lot more other things to plan rather than to add components.
