To convey ideas effectively,both aesthetic form and functionality need to go hand in hand, providing insights into a rather sparse and complex data set by communicating its key-aspects in a more intuitive way.

Wattenberg have suggested that anideal visualization should not merely communicate clearly, but stimulate viewer engagement and attention.!Data visualization is closely related to Information graphics, Information visualization, Scientiﬁc visualization and Statistical graphics.
