Abstract: A computer-implemented method, computerized apparatus and computer program product for hierarchical objects linkage data visualization. A visualization of linkage data comprising a plurality of connections between a set of source objects and a set of target objects is obtained with respect to a predetermined level of hierarchy defined over attributes of at least one of the sets, wherein attributes of the objects and connections therebetween are represented in the visualization as nodes and links of a bipartite graph respectively. A spatial layout of links of a node is modified based on a relative position of each neighbor node thereof in an adjacent level, wherein neighboring nodes represent attributes of one or more objects which share in common an attribute represented by the node, wherein the relative position is determined based on a visualization restricted to the neighboring nodes so as to obtain a position preserving layout.
