Hi Glenda and all, Just a side note. Maybe simplify and change "A particular presentation of the graphical is essential to the information being conveyed." to "A particular presentation of the graphic is essential to the information being conveyed." "graphical" is an adjective and typically describes a noun. My 2 cents.
