Kirk 2019 States Composition Is Reviewing Every Visual Property Of T
Kirk (2019) states composition is reviewing every visual property of the design. The final layer of design thinking concerned with composition involves how to position, arrange, and size all chart elements, interactive controls, and annotated components throughout the project. This process aims to achieve optimal readability while meeting the project's intent. Dividing composition into project-level and chart-level options can help identify and address areas of opportunity. This paper explores various composition strategies in the context of redesigning a visual project within constrained and challenging scenarios, including worst practices, space limitations, format transposition, data scalability issues, and trustworthiness concerns.

Introduction
Effective data visualization relies on strategic composition, which encompasses the deliberate organization of chart elements to communicate information clearly and persuasively. Proper composition enhances readability, guides the viewer’s attention, and maintains the integrity of the data presented. Conversely, poor compositional choices can lead to confusion, misinterpretation, or loss of trust. This essay describes two project-level and two chart-level composition options tailored to specific challenging scenarios, illustrating how design decisions can either mitigate or exacerbate issues within a constrained environment.
Worst Practice in a Limited Physical Space
When constrained to a fixed physical space—say, a small display area—the worst practice would be to utilize a cluttered layout that overflows or overlaps chart elements.
Project-Level Options:
1. Over-crowding all chart elements into the limited space: This involves cramming multiple charts, labels, annotations, and controls without regard for spacing or hierarchy, making the visualization unreadable. Implementing minimal whitespace intentionally to maximize data density exemplifies failure in composition. This degrades user comprehension and fails to prioritize important data, ultimately creating a chaotic interface (Few, 2009).
2. Using identical, small font sizes without differentiation: Employing tiny fonts across all labels, titles, and annotations disregards the need for visual hierarchy, rendering the information illegible. This demonstrates poor consideration of user readability in a limited space and violates foundational design principles (Tufte, 2001).
Chart-Level Options:
1. Overlapping data points or bars: Overlaying elements to conserve space causes obscured data, preventing interpretation and skewing insight. For example, overlapping bar charts without transparency or spacing leads to confusion (Kirk, 2016).
2. Eliminating margins or padding entirely: Removing white space around charts means axes, labels, and data points are directly adjacent, reducing clarity and overwhelming the viewer.
Reasoning:
These practices demonstrate hallmark errors—clutter, illegibility, and visual confusion—that exemplify the worst practice in a constrained space. They compromise the fundamental purpose of visualization: effective communication.
Using As Small a Space as Reasonably Possible
Maximizing space efficiency involves balancing information density with clarity. The worst practice in this context would be to compress all components unnecessarily, sacrificing legibility.
Project-Level Options:
1. Scaling down the entire visual disproportionately: Shrinking all elements without adjusting font sizes, spacing, or details results in components becoming unreadable or indistinct (Few, 2009).
2. Removing essential visual hierarchy cues: Eliminating differentiation in size, color, or weight causes the viewer to struggle in distinguishing main points from secondary information.
Chart-Level Options:
1. Compressing axes and labels tightly around the data: Tightening axes so labels are cut off or overlapping reduces readability and misguides interpretation (Kirk, 2019).
2. Removing gridlines and reference markers: Eliminating context cues makes data points less interpretable, especially in compact spaces.
Reasoning:
While space-saving is critical, excessive compression undermines clarity, defeats comprehension and diminishes trust in the data's integrity. Striking a balance is crucial; otherwise, the visualization becomes unusable.
Transposing from Landscape to Portrait (or vice versa)
Changing orientation impacts the visual flow and element placement.
Project-Level Options:
1. Rearranging layout to fit a portrait orientation by stacking horizontally aligned charts vertically: This preserves content but can lead to increased scrolling, which may hinder user engagement (Few, 2009).
2. Aligning chart components differently to fit vertical space—such as shifting legends to side, or repositioning annotations: Adjusting placement ensures compatibility but requires redesigning entire layout strategies.
Chart-Level Options:
1. Rotating axes labels and titles: Converting from horizontal to vertical labels may improve fit but can hinder quick reading unless carefully managed (Tufte, 2001).
2. Adjusting bar or line charts from horizontal to vertical orientation: This change alters data interpretation cues and may improve space utilization but requires reconfiguring data encoding.
Reasoning:
Transposing visualizations demands careful redesign to maintain clarity and user comprehension. Proper planning minimizes distortion of data storytelling and preserves visual hierarchy during orientation shifts.
Addressing Out-of-Page Data Scales and Refresh Needs
Dynamic data updates may cause scale inconsistencies that do not fit within the current page or display.
Project-Level Options:
1. Implementing adaptive or responsive scaling mechanisms: Automatically resizing visual components according to data scope avoids overflows (Kirk, 2016).
2. Designing multi-page or scrollable reports: Breaking complex data across pages or sections allows detailed views without overcrowding. Facilitates step-wise analysis.
Chart-Level Options:
1. Using zoomable or collapsible data points: Interactive features enable users to explore data subsets without expanding the entire scale (Few, 2009).
2. Adjusting axis ranges dynamically based on data refresh: Ensuring axes adapt to new data prevents misrepresentation or cutoff of critical information.
Reasoning:
Incorporating flexibility and interactivity ensures the visualization remains clear and informative despite evolving data scales, maintaining accuracy and user trust.
Enhancing Trustworthiness amid Skepticism
When management questions data integrity, the visual must reinforce credibility through transparent, honest representation.
Project-Level Options:
1. Transparency in data sourcing and processing: Clearly documenting data origins and transformation enhances transparency (Tufte, 2001).
2. Including confidence intervals and error margins: Visual markers indicating data variability and uncertainty reinforce honesty.
Chart-Level Options:
1. Using standardized axes and units: Consistent measurement scales prevent misinterpretation (Few, 2009).
2. Adding annotations that specify assumptions, data limitations: Contextual notes clarify the scope and reliability of the data.
Reasoning:
Trust is built by transparency and honesty in visualization design. Using clear, standardized, and informative elements addresses skepticism head-on.
Conclusion
Effective composition balances clarity, space, orientation, and credibility. Worst practices in constrained environments entail clutter, illegibility, misalignment, and opacity. Conversely, strategic project- and chart-level options—such as prioritizing minimal clutter, responsive scaling, and transparent annotations—serve to create meaningful and trustworthy visualizations. Recognizing and adjusting to challenges through deliberate design choices ensures that data communicates accurately, efficiently, and ethically.
