A chart creation tool is provided that operatively, specifies chart layouts interactively in lieu of programmatically specifying data transformations. Operatively, the herein described systems and methods can convert user-specified layouts into mathematical constraints, and a constraint solver is employed to draw the resulting chart. An illustrative user interface is provided that can allow a user to input data representative of one or more chart layouts through the interaction with one or more illustrative controls of the user interface. Responsive to such interactions (i.e., data input), one or more mathematical constraints can be calculated/generated from the inputted user-specified one or more chart layout input data. Illustratively, the chart layout can comprise a reusable layout.
