<p>The present invention discloses a graph service device and an operating method thereof capable of overcoming uppermost limits of existing graph visualizing applications by reducing calculation for a graph layout in order to visualize a large graph as a second level graph forming each community with each node is generated by forming each community grouped by at least one node among multiple nodes forming a first level graph, a layout by community is determined for each community formed in the first level graph when a layout of the second level graph indicating a position between nodes forming the second level graph is determined, and a layout of the first level graph indicating a position between the nodes forming the first level graph is determined by applying the layout by community of the first level to the position between the nodes in the second level graph layout.</p> |
