Graphs and the Space-Time Continuum

I was given a small hammer when I was just a wee lad. With hammer in hand, I wandered my home searching for something to fix. Later, my father had to retrace my steps with wood-filler and paint, repairing various door-frames, sills and mouldings. I don't do much with hammers anymore, the tools of my trade are software technologies. When I learn something new, its like getting a new tool and I go in search of an application. This approach is little non-optimal but it is how I learn. My latest interest are the data-structures known as graphs. Like most software engineers, I learned about graphs in school. Graphs are connected networks of nodes. One of the key points is that the connectivity of nodes is established by having nodes refer to other nodes.
I have never worked with anyone who has ever had the need to create a graph, including the Binary Search Tree. Today, most languages have built-in data-structures such as lists, hash-tables, and vectors. Data is modeled and stored in a database. It is easy to consign the graph to the realm of academia and the exotic. As others discount the graph, I may find a way to use it to my advantage, to make it a permanent part of my toolkit.
To begin, I close my textbook and strap myself into my rocket and launch to low earth orbit. Now adrift in vacuum, away from code examples and technical detail, I once again view the graph. Ignoring the obvious, such as computer networks, air travel routes, and state-machines, what do I see? Anything that interacts with anything probably is a graph. One of my favorite tools is Object-Oriented design. Interacting objects are more exciting to me than functional flow. Interacting objects are nothing more than nodes in a graph.
Can I enhance my ability to model the world with OO by thinking in terms of graphs? Will graphs add a new perspective to my ability to analyze?
Next I dock with my star-ship and warp out of the solar-system. I subject the graph to various experiments. One thing to note is that a graph can exist in three dimensions. Perfect examples are Tinker Toys and Connects. But 3-D graphs can be squashed flat and still exist in 2-D. Therefore it is easy to surmise that graphs of many dimensions exist and can be represented in just two dimensions. Infinity in two dimensions.
Now I launch the graph at the event-horizon of a black-hole. As the graph compresses, the intent of each node become distorted. Yet the relationships remain. The differences between each node becomes less as they merge to a singularity and become one. One node associated with itself. With trepidation, I leave the void, with the memories of that brave graph emblazened in my mind. I return home, reopen my textbook and begin my journey anew.
