Graphics?


What is it? Graphics are visual presentations on a surface, like canvas, or on a computer or just on paper. This is very common nowadays. Whenever there are numbers, how do we represent them? Graphs are used to represent them, like a histogram, column graphs, cumulative frequency graph, and so on and on. But, these are not all. Some other examples include photographs, drawings, graphs, diagrams, typography, numbers, symbols, geometric designs, maps, or other kinds of images. Graphics often combine illustration, text and colour.


But, what are graphics used for? Graphics are used for several things, like to represent ideas, which are very important nowadays. When we have ideas, some people may not understand them clearly, so such graphics become very useful. Graphics are not very modern, because they have existed since the stone age, when the people used to draw on the walls of the caves to tell stories. So, graphics had importance in the past, and they have that importance today too. But, today they are used more than before.
