Generally speaking, the word graphic refers to writing or printing and everything related to them. But also, by graph, it is understood the representation of data, almost always numerical, although it can also be figures or signs, through surface lines or symbols to determine the relationship between them.
Meanwhile, a set of points can be given that will be expressed in Cartesian coordinates and will serve to analyze the behavior of a given process or a set of signs or elements that allow us to decipher or interpret some phenomenon, among other issues.
We can find different types of graphs, the most common are: numerical, used to represent the behavior or distribution of quantitative data of a population. This type of graphic manifests itself through visual images. On the other hand, the linear ones will represent the values in two orthogonal Cartesian axes to each other. More than anything, this type of graph is recommended when you have to represent series over time, since it allows you to show maximum and minimum values of a question.
Another type is bar graphs, which will be used when you want to highlight the representation of the percentages that refer to a total. The bars allow the representation of frequencies and can be drawn horizontally or vertically, generally used to represent bar graphs are called worksheets.
Then there are the pie charts that will allow us to observe the internal distributions of data that represent a fact, also in the form of percentages over a total. According to the interest of what you want to highlight, what you do is separate the sector corresponding to the highest or lowest value. And finally, histograms, another very common type of graph, which will be used when you want to represent samples grouped in intervals. It is formed by rectangles connected to each other, whose vertices of the base must coincide with the limits of the intervals.
At present, science, technology and information technology have developed processes that allow graphic information to have a greater presence in the media and, therefore, in the community.
