Abstract
An augmented spreadsheet presentation provides for selecting a region of user focus in a primary body of data displayed as an array of cells, with two or more displayed cells of the array of cells being logically linked by a constraint graph. Color of two or more displayed cells can be dynamically adjusted in response to selected user focus with a mouse or other cursor, with each of the two or more displayed cells having a slightly different color to form a color gradient that shows constraint graph linkage of the cells. Additional annotations illustrating constraint graph relationships or formulas can also be activated by a transient mouse focus.
