Construction of Diagrams| Practical Work in Geography Class 12

The Construction of a Diagram is a part of the Practical Work in Geography of Class 12. The subpart belongs to the chapter named Graphical Representation of Data. The subpart Construction of Diagrams describes the diagram types and the construction process of them in a general way.

In this article, we are going to discuss the Practical Work in Geography Class 12 with the Construction of Diagrams.

Construction of Diagrams

The Construction of Diagrams and the processing of data is based on so many different categories like length, width, and volume. Based on these data and datasets, we can plot these diagrams by mentioning their characteristics. The diagrams can be grouped into different types as mentioned below:

• One-Dimensional Diagram – These types of diagrams mainly use height and length as a linear form to compare something. These types of representations are simple. Examples: line graph, polygraph, bar diagram, histogram, etc.
• Two-Dimensional Diagram – A dimensional diagram is generally used to represent the data and information by simply using two dimensions. These type of diagrams deals with complex datasets. Example: Pie Chart and Rectangular Diagram Chart.
• Three-Dimensional Diagrams – The three-dimensional diagrams are majorly known as the volume of a diagram. These types of diagrams consider the length, width, and height of the element to depict it in the form of a diagram. Example: Cube and Spherical Diagrams.

Construction of Diagrams – General Tips

Here are some major tips to construct a diagram as mentioned below.

• Understanding The Purpose: Before constructing a diagram, it is necessary to understand the purpose of the diagram. It is necessary because each diagram comes with its own complexity and process.
• Gather The Necessary Information: We need to collect the information to represent them in a diagram. These data may include some data sources, different scales, and other data.
• Select The Right Diagram: You need to choose the right diagram to depict the whole data.
• Prepare a sketch and Outline: Before the final diagram, you need to create the outline of the final diagram. This sketch will help you understand the process of how to complete the actual diagram.
• Add Necessary Details: You need to add the necessary details when you are attempting the final graph. These can be the axis name, units, and so on.
• Check The Accuracy: Check the diagram for its accuracy. You need to check all the elements once you think you have completed the diagram.

Different Types Of Diagrams

There are so many different types of the diagrams as mentioned below.

• Line graphs: The line graphs are used to plot a graph that uses the lines to connect the all data.
• Bar diagrams: The bar graph is used to depict the rectangular bars to represent the data.
• Pie diagram: The pie diagram represents the raw data set in a circular form.
• The wind rose and star diagram: The wind rose is another circular data that shows the speed and way of the air. The star diagram depicts the data of events or tasks in a circular formation.
• Flow Charts: The flow charts are those diagrams that represent the process of any workflow.

Construction of Diagrams- FAQs

What is a geographical diagram?

A geographic diagram is a diagram in the field of geography, the field of science devoted to the study of the lands, the features, the inhabitants, and the phenomena of Earth.

What is a diagrammatic representation of geographic data?

The representation of statistical or geographical data in the form of bars is called bar diagram.

What are the methods of geographic data representation?

Two methods of representing geographic data in digital form are raster and vector. In principle, both can be used to code fields and discrete objects, but in practice there is a strong association between raster and fields and between vector and discrete objects.

What is the importance of diagram in geography?

Statistical graphs and diagrams help students to summarize huge and a wide range of information for future analysis. Diagrams and graphs hold huge information in accurate way. The geographers can identify and interpret the relationship existing between various variables.

What are types of diagrammatic?

Line diagrams, bar diagrams, and pie charts are the three primary forms of diagrams utilised in statistical analysis. A further subdivision of bar diagrams into basic bar diagrams, numerous bar diagrams, and component or sub-divided bar diagrams is a possibility.

What are the main types of geographic data?

The two main representation models are the raster model and the vector model. Layers using these models are commonly known as raster layers and vector layers.

What is the main purpose of the diagram?

A diagram gives a visual representation of something given in a text or oral format. A title in a diagram explains what the diagram is about. Labels in a diagram are used to identify various parts of the diagram. Captions of diagrams give additional information about the diagram.
