Discussion 1: My choice of compound visualization I choose the pie chart as the potential technique regarding data visualization from the table of the visualization. The pie chart is a statistical graph in the circular shape which is divided into several parts according to the various numerical percentages. The arc length of the circle represents different quantities of data. It is beneficial for representing many data points within a single frame. Additionally, the comparison between different data sets can also be made using the pie chart.
The pie chart is particularly effective in analyzing qualitative data (Kirk, 2016). It is associated with categorical data, generally represented in percentage form. Multiple data comparisons can be visualized with varying angles of the circular segments, making it easy to interpret proportions. An example where pie charts are generally used is in representing voter percentages. The entire circle depicts the total number of voters, with each segment representing different groups such as those willing or unwilling to vote. The angles in the pie chart illustrate the proportion of each group — for example, those willing to vote versus those abstaining.
However, the pie chart has limitations; it cannot effectively represent quantitative data where the length or size of objects needs to be compared directly. It is primarily suited for showing parts of a whole in a percentage or proportion context, rather than detailed numerical differences.
My second choice for compound visualization is the rich picture. A rich picture is a drawing of a specific situation that helps illustrate key objects and their relationships to improve understanding. It employs symbols, icons, and pictures to represent elements within a framework clearly. This technique is useful for simplifying complex situations by visually representing all relevant components and their interactions.
The rich picture technique provides valuable support for evaluating the most important aspects of a situation, especially during pre-analysis stages. It allows stakeholders to identify and configure the critical elements that influence processes or systems (Bell, Berg & Morse, 2019). A typical example of this technique is in organizational management, where it visually maps out processes, roles, and relationships within a company to identify areas for improvement. It helps organizations focus on key activities that need enhancement or realignment to optimize performance.
Nevertheless, the rich picture has its limitations; it may not effectively capture or represent scenarios with multiple or highly dynamic events that change frequently. Activities or relationships that are isolated or insignificant to the overall process may not be depicted effectively, potentially leading to incomplete or superficial understanding of the situation.

Data visualization plays a crucial role in transforming raw data into interpretable and insightful visual formats that aid in decision-making and understanding. Among various techniques, the pie chart and rich picture stand out as effective tools for different contexts and data types. Understanding their characteristics, applications, and limitations provides a comprehensive view of how visualization enhances data interpretation.
The Pie Chart: Analyzing Categorical Data
The pie chart is a widely used visualization tool for representing qualitative, categorical data in percentage form. Its circular shape is divided into slices or segments, each corresponding to a category’s proportion relative to the whole. The length or size of each segment’s arc reflects the percentage that particular category contributes to the total dataset. As Kirk (2016) emphasizes, pie charts are effective in providing an immediate visual impression of comparative proportions, making them suitable for displaying data such as market share, election results, or survey responses.
The strength of pie charts lies in their simplicity and ease of understanding. They allow viewers to quickly grasp the relative sizes of different categories and compare them at a glance. For instance, in electoral analysis, a pie chart can visually depict the percentage distribution among candidates or parties, making the proportions evident without requiring detailed numerical analysis. This visual clarity aids stakeholders in making rapid assessments of data distributions.
However, pie charts are not suitable for displaying quantitative comparisons involving precise numerical differences. They should be used when the focus is on the parts of a whole rather than exact numerical values. Furthermore, when many categories are involved, pie charts can become cluttered and difficult to interpret, diminishing their effectiveness.
The Rich Picture: Visualizing Complex Situations
The rich picture technique is a graphic method designed to illustrate complex systems or situations holistically. It employs symbols, icons, and pictures to portray various components, roles, and relationships within a scenario. This visual approach facilitates a comprehensive understanding of multifaceted issues by capturing the interconnectedness of elements involved (Bell, Berg & Morse, 2019).
The primary application of the rich picture is during pre-analysis phases, where stakeholders seek to identify key factors, problematic areas, and systemic relationships within an organization or process. For example, in organizational management, a rich picture can map out workflow processes, stakeholder interactions, and resource allocations. Such visualization helps identify bottlenecks, redundancies, and opportunities for improvement.
The technique supports participants in gaining new perspectives by visually integrating diverse viewpoints, which may be difficult to reconcile analytically or textually. It is particularly useful for facilitating communication among multidisciplinary teams and for fostering shared understanding of complex issues.
Nonetheless, despite its advantages, the rich picture is less effective for scenarios requiring precise quantitative analysis or detailed data comparison. It focuses more on qualitative understanding, which may oversimplify or overlook subtle numerical differences. Additionally, creating an accurate and comprehensive rich picture relies on stakeholder participation and can be time-consuming.
Comparative Analysis of Visualization Techniques
Choosing an appropriate data visualization method depends on the nature of the data, the context of analysis, and the intended audience. The pie chart excels in representing proportions within a whole for qualitative datasets, offering quick insight and straightforward comparison. Its simplicity makes it suitable for presentations where immediate visual understanding is necessary.
Conversely, the rich picture fosters a deeper qualitative understanding of complex systems by illustrating interactions, roles, and relationships. It supports strategic planning, problem analysis, and holistic evaluations. It is especially advantageous in scenarios that require exploring interconnected components rather than precise numerical data.
Both techniques have limitations that should be considered. Pie charts are less effective with many categories or where precise data comparison is needed. Rich pictures may oversimplify or omit subtle quantitative details and can be resource-intensive to develop.
In practice, combining these visualization techniques can offer comprehensive insights—using pie charts for quantitative parts-of-a-whole analysis and rich pictures for exploring systemic complexities. Such integrated approaches enhance decision-making processes and facilitate communication across diverse stakeholder groups.
Conclusion
Data visualization is an essential aspect of effective data analysis and communication. The choice of visualization technique must align with the data type, analytical goals, and audience. Pie charts serve well for illustrating proportional relationships among categories, making them useful in presentations, reports, and basic analyses. Rich pictures, on the other hand, excel in depicting complex systems and relationships that underpin organizational or systemic processes.
Understanding their respective strengths and limitations enables analysts to employ these tools strategically, thereby maximizing their impact in conveying insights and fostering understanding. As data becomes increasingly complex, integrating multiple visualization methods will become ever more critical in producing clear, comprehensive, and actionable insights.
