For me a knowledge graph is a complex network. When you try to grasp any complex topic your brain starts to build and connect a fuzzy network of topics and their respective positive or negative correlations and of course the weights between the connections. Once you have unfuzzied the picture in your head you realize that the network is active and dynamic and that this network has different "modes" of operation and that some weights and correlations can change over time, while others are always static. Mastering the dynamics of the knowledge graph is the final step in understanding it.
