diagrammatic representation of geographical data


Usually, laymen find it difficult to understand and interpret a graph. The arrow symbol represents relationships. feature the data effectively, as you can see in the example on the next page. All rights reserved. Those diagrams which are based on a single set of numerical data are called simple bar diagram. For example, income and expenditure, imports and exports, marks obtained in different subjects in different classes. We can locate the position of a point in terms of its distance from both these axes. Usually, graphs are used to present time series and frequency distributions. In graphs, it is represented using two lines called coordinate axes. Principles of Graphical Representation. The point at which two lines intersect is called an origin ‘O’.

Ø Different types of data representations methods are: (1). We cannot use a graph in support of a statement. Usually, graphs are used to present time series and frequency distributions. Notice how the geographical features have been pared down and visually subdued to allow the data to stand out. Data structure diagram (DSD) is a diagram of the conceptual data model which documents the entities and their relationships, as well as the constraints that connect to them.. A diagrammatic language, as John Walker explains, employs a variety of means to encode information and every single element inside the map has a specific function. Data structure diagrams are most useful for documenting complex data entities. What is a variable?In statistics, a variable has two defining characteristics:A variable is an attribute that describes a person, place, thing, or idea.The value of the variable can "vary" from one entity to another.For example, a persons hair color is a potential variable, which couldhave the value of "blond" for one person and "brunette" for another. Maps, where geographical accuracy has been abandoned in favour of clarity and has been replaced by a diagrammatic language, are called diagrammatic maps. For example, the distribution of the Indian population by their working status.
