Complete the "Forensic Designs Assessments" Exercise located at the following link: FORENSIC DESIGN ASSESSMENTS This task relates to a sequence of assessments that will be repeated across Chapters 6, 7, 8, 9 and 10. Select any example of a visualisation or infographic, maybe your own work or that of others. The task is to undertake a deep, detailed ‘forensic’ like assessment of the design choices made across each of the five layers of the chosen visualisation’s anatomy. In each case your assessment is only concerned with one design layer at a time. For this task, take a close look at the data representation choices: Start by identifying all the charts and their types How suitable do you think the chart type choice(s) are to display the data? If they are not, what do you think they should have been? Are the marks and, especially, the attributes appropriately assigned and accurately portrayed? Go through the set of ‘Influencing factors’ from the latter section of the book’s chapter to help shape your assessment and to possibly inform how you might tackle this design layer differently Are there any data values/statistics presented in table/raw form that maybe could have benefited from a more visual representation?

The increasing reliance on visualisation and infographics for data communication necessitates a meticulous approach to evaluating their design effectiveness. The forensic assessment of visualisations involves dissecting each layer of design to understand the choices made and their impact on data comprehension. This paper presents a comprehensive forensic analysis of a selected infographic, focusing on five key layers: data, visualisation type, marks and attributes, gestalt principles, and contextual elements. The primary aim is to determine how well these layers contribute to clear and accurate data storytelling and to suggest improvements based on established design principles.
The chosen visualisation for this assessment is a bar chart illustrating the annual revenue growth of a multinational corporation over a ten-year period. This example was selected due to its widespread use and the complexity that can be embedded within seemingly simple visualisations. Our first focus was the data layer, which involves scrutinising the raw data presented. The dataset included annual sales figures, profit margins, and market share percentages. It appeared comprehensive; however, inconsistencies in data recording dates and profit margins could potentially distort interpretation. Ensuring data integrity is fundamental to effective visualisation, and in this context, a more transparent presentation of data sources and validation methods would have strengthened credibility.
Moving to the visualisation layer, the choice of a bar chart is appropriate given the focus on showing growth trends over time. Bar charts are effective for comparative analysis and temporal data, but their suitability diminishes when attempting to depict nuanced changes or complex relationships. In this case, the bars effectively conveyed overall revenue increase; however, incorporating a line graph or combo chart might have better illustrated the trajectory and fluctuations within the period. The chart type should align with the specific analytical goals of highlighting growth patterns and volatility.
Examining the marks and attributes layer, each bar’s height corresponded accurately to revenue figures, with consistent colour coding across years. Still, the use of colour gradients or additional visual cues could have enhanced differentiation, especially for viewers with colour vision deficiencies. The axes labels were clear; however, the axis scales could have been optimised to avoid misleading interpretations. For instance, employing a logarithmic scale or adding gridlines might have helped viewers accurately assess percentage increases rather than absolute differences.
Applying the gestalt principles—proximity, similarity, closure, and continuity—revealed some valuable insights. The proximity of bars should ideally group related data points or categories; in this visualisation, temporal proximity was maintained correctly. Similarity through colour coding was consistent, aiding pattern recognition. However, the lack of visual continuity—such as connecting lines—missed an opportunity to help viewers perceive overall trends more seamlessly. Incorporating trend lines or annotations aligned with gestalt principles would have improved gestalt clarity and facilitated quicker comprehension.
Finally, the contextual layer involves considering how well the visualisation integrates into its intended communication setting. The infographic included contextual cues such as titles, annotations, and source attributions, which aligned well with the goal of conveying growth insights to stakeholders. Nonetheless, adding contextual background about market conditions or industry-specific factors could have provided richer interpretative context, helping viewers understand the data beyond the numerical trends.
In conclusion, this forensic assessment highlights critical areas where the visualisation performs effectively and opportunities for enhancement. Appropriately selecting chart types, optimising data representation, employing gestalt principles for visual clarity, and providing contextual richness all contribute to more effective data communication. Future visualisations should consider these forensic insights to ensure clarity, accuracy, and user engagement, thus fostering better data-driven decision-making.
