Enhancing graph visualization with supplemental data

A computer system, comprising one or more processors, one or more memories, and one or more computer readable hardware storage devices, said one or more hardware storage device containing program code executable by the one or more processors via the one or more memories to implement a method for communicating supplemental data for nodes of a graph, said method comprising:

• dividing, by the one or more processors, a visual representation of the graph into a plurality of portions of a computer screen, each portion of the visual representation of the graph being a rectangle corresponding to a respective node of the graph, wherein said dividing the visual representation of the graph comprises determining a number of pixels in a plurality of rectangles displayed on the computer screen along with the graph;
• encoding steganographically, by the one or more processors, supplemental data for each respective node, together with an offset distance between a reference point of each respective node and a reference point of the supplemental data for each respective node, into the portion of the graphical representation corresponding to each respective node;
• prioritizing, by the one or more processors, fixed length attributes related to the respective node, and
• encoding steganographically, by the one or more processors, the attributes into the rectangle corresponding to the respective node, said encoding starting with a highest priority attribute of the fixed length attributes and continuing sequentially according to a priority of the remaining attributes of the fixed length attributes.

A computer program product, comprising one or more computer readable hardware storage devices having computer readable program code stored therein, said program code containing instructions executable by one or more processors of a computer system to implement a method for communicating supplemental data for nodes of a graph, said method comprising:

• dividing, by the one or more processors, a visual representation of the graph into a plurality of portions of a computer screen, each portion of the visual representation of the graph being a rectangle corresponding to a respective node of the graph, wherein said dividing the visual representation of the graph comprises determining a number of pixels in a plurality of rectangles displayed on the computer screen along with the graph;
• encoding steganographically, by the one or more processors, supplemental data for each respective node, together with an offset distance between a reference point of each respective node and a reference point of the supplemental data for each respective node, into the portion of the graphical representation corresponding to each respective node;
• prioritizing, by the one or more processors, fixed length attributes related to the respective node, and
• encoding steganographically, by the one or more processors, the attributes into the rectangle corresponding to the respective node, said encoding starting with a highest priority attribute of the fixed length attributes and continuing sequentially according to a priority of the remaining attributes of the fixed length attributes.
