In one embodiment, a computer-implemented method comprises receiving a first user instruction in a controller. The controller stores information about a first plurality of metaquarks and a first graph topology creating expression. The method further includes generating, by the controller, an original graph topology based on the first plurality of metaquarks and the first graph topology creating expression and the first user instruction, and generating first display information based on the original graph topology. The method may further comprise receiving a second user instruction in the controller; generating a second plurality of metaquarks and a second graph topology creating expression based on the second user instruction; generating, by the controller, a modified graph topology based on the first plurality of metaquarks, the second plurality of metaquarks, and the second graph topology creating expression; and generating second display information based on the modified graph topology.
