GraphSight is a convenient tool to plot and explore 2D math functions. You may plot several function in the same window, create several coordinate spaces defined by different variables (not only those y and x), set labels on the plot, use custom user-defined constants in every formula. All of the graphical objects on the plot are much interactive (i.e. they allow dragging, react to mouse clicking and moving). GraphSight gives you a full control over a coordinate space which can be shifted, and zoomed with the only help of mouse. GraphSight has come as a realization of the idea: 'A graph does not have to be dead'. The program is based on the strong object-oriented concept by which every graphic object in GraphSight is a real interactive object and not a stark picture.
