Effective communication goes beyond mere words. It depends on illustrations and other visual aids for conveying and clarifying complex ideas and enhancing understanding. In this chapter you will learn how to identify, interpret and use illustrations such as graphs, maps, diagrams effectively in your academic undertakings.
The competence developed in this chapter will enable you to make an effective interpretation of illustrations and effectively use them in academic documents.
Identifying simple and complex illustrations
Illustrations are visual representations meant to enhance reader’s comprehension or convey ideas. Illustrations in academic documents can be classified into two main categories namely: simple and complex illustrations.
Simple illustrations
They are typically used to conyey straightforward concepts or ideas. These can include diagrams, charts, graphs, or simple line drawings. They are frequently used to enhance the text and present information directly and clearly. They can facilitate the reader’s understanding of the main ideas and are typically simple to understand. Simple illustrations include line graphs, bar charts, pie charts, diagrams, flowcharts. Simple illustrations are characterised by the following features: they are clear and straightforward, they use minimal detail and they are easily recognizable shapes and patterns.
Simple illustrations in academic documents play the following roles:
Improve reader’s comprehension: They can help readers better understand complex information by presenting it in a more reachable and spontaneous format.
Summarize key points: When used correctly they can effectively sum up and highlight the main points from a text and in that way make it easier for readers to capture the essential points.
Facilitate analysis and interpretation: The use of graphs, charts, and diagrams can assist readers in interpreting and analysing data presented in other forms that may be difficult to realise through text alone.
Enhance engagement: visual aids are also meant for creating visual appeal of a document. A well-designed simple illustration can make the academic document more visually appealing and engaging, which can improve the overall reading experience.
Complex Illustrations
These present more detailed or layered information. The are more detailed and complex visual representations involving a variety of elements such as multiple subjects, complex backgrounds, detailed quality, and detailed shading or colouring. They often require a significant amount of time and skill to create due to their level of detail and the complexity of the elements involved. Complex illustrations can be of various forms, including digital art, traditional art, scientific illustrations, fantasy artwork, technical drawings, and more.
Specific complex illustrations include maps with multiple layers of data, info-graphics and technical drawings with complex details. Complex illustrations are characterised by richness in detail, multiple components and complexity that call for closer examination for full understanding.
Interpreting illustrations
The interpretation of illustrations is a process in which data are recognised and scrutinised for their meaning. A good way to realise the key points of the illustration is to describe the idea of the illustration clearly. You should also attempt to relate the main ideas of the illustration with the results of an experiment or research, Most questions based on an illustration will require differentiation of what is in the illustration’s idea compared to actual data. To interpret illustrations effectively, consider the following basic steps:
(a) Analysing key elements
Analyse the illustrations used in a document regarding the message the author intends to communicate. An illustration can make an abstract idea more concrete, easier to imagine, and closer to both the writer and the reader. Likewise, you can simply explain an unclear or complicated phenomenon using an illustration. It makes the simplified image closer to the original and easier to understand. At its simplest level, an illustration can substitute for verbal and written explanations by communicating the same message but in a different form.
The key elements to be analysed include the shape, colour, proportion, space, pattern, percentage, texture and the message the writer delivers The artist’s skill greatly influences the effectiveness of an illustration in communication. However, an appropriate interpretation of what an illustration adds to the communication increases the value of that illustration.
(b) Understanding the message
The interpretation of the illustrations normally focuses on the message we get. The message must not be specific to the text but must be understood universally. The relationship between an illustration’s message and the text usually differs with each type of illustration. Interpreting the message of the illustration without the text first is an essential step as it will help to see how the illustration relates to the text. It allows critical evaluation of the illustration without getting any clue from the text or a story. This will make the reader think critically about the story or the text.
Relating illustrations to the text
Illustrations such as graphs, tables, or pie charts can be drawn. Ideas from the information in the text provide a concrete connection between the illustration and the idea of the text. Relating illustrations to the text allows the presenter to assess the audience’s understanding of the concept. Sometimes, illustrations and other visual aids convey information not found in the texts. In these cases, the reader should treat the illustration separately. They can interpret the illustration as if there is no text related to the illustrations. Then, they can compare what they have interpreted with the information found in the text.
This technique helps develop English for academic communication.
Importance of illustrations
Illustrations are crucial for displaying information and simplifying the interpretation of complex data. Generally, illustrations play the following roles:
(a) Enhancing understanding
All illustrations, including charts, graphs, maps, photographs, video stills, diagrams, and cartoons, can be effective when used to facilitate understanding.
(b) Visual appeal
When an assignment is first presented, the first thing a reader will notice is the visual layout. Most of the time, readers tend to assess the illustrations of the document before digging into the text and form early opinions based on how the information is set out.
(c) Conveying information efficiently
A simple illustration can transfer information more effectively than a large text. To present complex information for technical writing, for example, the author can use illustrations to serve the purpose of his document.
