Data Visualization

In the 21st century, organizations have been continuously growing, serving more consumers daily, and some have gone to the extent of becoming global. Technological advancements have been the major contributing factor to this development. Most of these institutions have recognized the importance of data and the stored information. With such, they are using this information towards the overall expansion of their boundaries. For example, organizations are using the big data stored towards making critical decisions that influence their profitability and future. Others are using the data towards seeking patterns and hidden trends that will bring significant benefits. However, the use of such information requires a clear presentation of the data, which is referred to as data visualization. According to Blackwell, Nikou, DiGioia, and Kanade (2000), data visualization is the process of graphical presentation of information and data. This practice is enabled through the application of elements such as charts, maps, and graphs. In this paper, there will be a review of the various aspects applied in the process of data visualization, their importance, an instance of use, and their applicability in presentations.

Impact of Headings and Introductions

The technical presentation is the process by which experts in a particular field such as engineering, medicine, among others, present their visual perspective concerning a specific topic at hand. During this process, they offer their ideas, views, and understanding that are mainly aimed at improvement or bringing positive changes. In the course of these presentations, there is a necessity of applying headlining and introductions.

Headings

A heading is basically a title of a page or document. A significant impact on the application of heading is that there is a presentation of key concepts and supporting ideas in the presentation. It also creates some understanding and prepares the audience for the content of the paper. For example, a document can have a heading reading "Importance of Data Collection in Research." With such a heading, the audience will automatically expert the content in the paper talks about data collection and how it is significant in research (Lorch et al., 2001). Thus, headings have an impact on creating an overall outline of a presentation and enables the audience to navigate the content of the presentation.

Introduction

An introduction is a formal presentation and the formal initiation of an idea in a presentation. Introductions are different from headings because a title will usually a few words in a sentence. However, an opening is a collection of aa few sentences, i.e., a paragraph explaining the topic at a wide range. An introduction has a significant impact on providing a first impression in a paper. With a good introduction, a presenter will catch the attention of the presenter. Thus, a good introduction will mean the audience will pay much attention; a bad/non-catchy introduction will not catch the attention of the audience (Samraj, 2002). Hence, openings have a significant impact on grabbing the attention of the audience.

Chart Labeling, Captions, References and Footnotes

During presentations, various tools have to be applied. Chart labels, captions, references, and footnotes are some of these elements. Nevertheless, all these fundamentals have different uses and are applied differently in the course of a presentation.

Chart Labeling

In the course of a presentation, there is the application of charts. A chart is a sheet of information in the form of a table or diagram that is used to presents some statistics of data. There are various types of maps that can be applied in a presentation, which include but are not limited to pie charts and bar graphs. The primary importance of using a figure is that it enables the display of data/information. As the name suggests, chart labeling is the art of providing necessary information concerning the chart. Through the achievement of this visual presentation and labeling, organizations can use this to convey information and make sense of the data.

Applicability and Instance of Use

In a presentation, charts that are accompanied by adequate labeling are applied when specific data is compared or internalized. For example, instead of explaining in theoretical terms, the units of sales made monthly in an organization, there is an application of a chart. The image below described the outline of the graph.

Figure 1: Chart showing both units sold and total

Caption

In a presentation, there may be the use and application of images, videos, or any form of diagrams. With the use of this, there is a necessity to give a brief explanation of the picture or video used; this is archived through adding a small piece of text underneath the diagram, which is referred to as a caption. Thus, captions are relevant because they provide first-hand information concerning a picture used in a presentation.

Applicability and Instance of Use

Captions applicability mainly depends on the specific element being dealt with. Accuracy depends on naming the item precisely, either a diagram or table. Captions are used when there is an image in the presentation. For example, the chart below has a caption below it reading; “Chart showing both units sold and total” thus, this element is used when trying to name a figured used in a presentation.

References

References are not only used in presentation but also formal and academic documents. References can be described as the process of providing precise documentation of the various external sources used in the presentation. Thus, this element is crucial since it aims to provide proof and accuracy of the information presented.

Applicability and Instance of Use

The applicability of references mainly depends on the accurate citation of the information. On the other hand, they are explicitly used when the investigator has used external data in the course of preparing the presentation.

Footnotes

Footnotes are pieces of additional information that are printed on the bottom of a presentation spreadsheet or page. They are essential in that they give a reader insight into the research; also, they add a level of clarity to the information in the presentation.

Applicability and Instance of Use

There are no specific application techniques for footnotes. However, they are to be used in any presentation and explain the data presented in a document.

Typography and Its Importance

Typography is the art of arranging letters and text in a certain way to aim to make the document or presentation visually appealing or legible. This practice mainly involves the font style, structure, and appearance of text. For example, Garamond, Times New Roman, Arial, and Calibri are some types of typography that can be used in a text document. Thus, in a more straightforward meaning, typography mainly implies the various fonts used in a report. Typography is important because it establishes a strong visual hierarchy and communicates the tone used in a presentation (Myung, 2003). Hence the typography in a presentation is critical because it conveys some emotions and specific messages to the audience.

Functional Decoration and Data Legibility

In a presentation, there is a necessity to apply functional decorations, which can be done by incorporating various colors. According to Ilbahar and Cebi (2017), the functional decoration is the process of decorating the content of a presentation through which different expectations can be shifted or distorted from the rational perspective. The decorations aid in the process of amplifying the message with the surroundings of the data. Functional decorations are archived through three types of colors. Complementary colors: this is referred to as the traditionally RYB model. It comprises of red-green, yellow-purple and blue-orange. Analogous colors refer to colors that correspond to each other in a particular manner, for example, red-orange. Triadic colors: this is a scheme that applies colors that evenly mixed up. It utilizes a pale and unsaturated version of the colors. There are mainly three triadic colors, which include; red, yellow, and blue. However, despite the application of these colors, data legibility must be maintained. Data legibility is the ability of an audience to read and understand specific data presented in a presentation (Stamps, 2004). Hence, there has to be a precise balance between the functional decorations and data legibility.

Presentation Layout, Arrangement, and Sizing

The presentation layout is the process by which the general presentation is formatted, positioned, and strategically placed. The layout presents a plan or a design that is applied in the arrangement of the content in the presentation. Thus, presentation layout is the primary design in which the details are laid out. Moreover, a presentation incorporates the art of the precise arrangement of the details. The arrangement refers to the process the details are planned and laid in the document or spreadsheet. Lastly, there is a significant consideration of the sizing; this refers to applying a particular measure in a presentation.

In conclusion, in the course of a presentation, the general format must be taken into significant consideration. The typography, functional decoration references, captions, among others, must be studies and met according to the precise criteria. Hence, an investigator must take into account the physical aspect of a presentation.
