Layout method and system of dynamic unconnected network in display region

The invention discloses a layout method of a dynamic unconnected network in a display region, wherein the dynamic unconnected network comprises a plurality of connected components. The layout method comprises the steps of: sequencing the connected components according to the importance; segmenting the sequenced connected components into a first subset S1 and a second subset S2 according to the order first of importance, wherein the first subset S1 at least comprises a connected component with maximum importance; segmenting the first subset S1 into an upper subset Cp and a lower subset Cm according to order second of importance, wherein the upper subset Cp only comprises the connected component with maximum importance; proportionally dividing the display region into display parts S1' and S2'according to the importance values of the first subset S1 and the second subset S2; proportionally dividing the display part S1' into display parts Cp' and Cm' according to the importance values of the upper subset Cp and the lower subset Cm; and repeatedly executing the first segmentation and the second segmentation and corresponding display region division until the aspect ratio of the displaypart Cp' is close to 1. By the method of the invention, the dynamic unconnected network is more clear and has large-information content layout; or the evolution of the dynamic unconnected network is more stably and smoothly displayed when the dynamic unconnected network is updated.
