Nodal architecture

Nodal architecture is like a network of roads. It's made up of lots of points (or 'nodes') connected together. Each node is like a street corner. When you drive down the road, you can turn left or right (or sometimes even go straight) at each street corner. So nodal architecture is like a network of roads - with lots of possible routes that you can take to get from point A to point B.
