1. A method for managing and rendering one or more information nodes relative to a current focus, the method comprising: receiving, by a processor, one or more principal topics from a content of one or more information nodes, wherein the one or more information nodes includes at least one first information node; determining, by a processor, a topic vector from a similarity of a content of the first information node to the one or more principal topics; creating, by a processor, a map from the topic vector to a storage location of the first information node; determining, by a processor, one or more current topics from a content of a second information node, wherein the second information node is an information node that has been accessed recently; determining, by a processor, a current focus vector from a similarity of the one or more current topics to each of the one or more principal topics; and rendering, by a processor, a representation of the current focus vector and a representation of the first information node according to a rendering algorithm, wherein the rendering algorithm determines a position and a size of the representation of the current focus vector and of the first information node.
