Why Do We Need To Understand Data Visualisations There Is More And M

Why do we need to understand data visualisations? There is more and more data around us, and data are increasingly used in decision-making, journalism, and to make sense of the world. One of the main ways that people get access to data is through visualisations, but lots of people feel like they don’t have the skills and knowledge to make sense of visualisations. This can mean that some people feel left out of conversations about data.

Please conduct the following activity located at the following address: Tell us what you think of the visualisations that we used in our focus group research. Instructions below!

What to do:

1. Look at the visualisations by clicking on the images below. You can choose to open the visualisation in a NEW tab or window (we recommend this) or view it in a pop-up window if you prefer to stay on this page. Some are interactive (i) and some are static (s).
2. Place the images on the grid. When you’ve looked at one, go to the grid and position the image according to whether you liked or didn’t like and learned or didn’t learn something from the visualisation (‘learning something’ could also mean confirming something you already knew). Only place the visualisations that you have looked at onto the grid. Click SUBMIT.
3. Compare your views with others. You can compare your responses to the visualisations with those of others, by clicking COMPARE. Choose three of your favorite visualisations. Post a 3 – 5 sentence summary of why you chose the visualisations. What caught your attention? Were they effective in presenting the provided data? If possible, explain how you would do to improve the visualization?

Understanding data visualisations is increasingly essential in today’s data-driven society. With the rapidly expanding volume of data generated every day, visualisations serve as crucial tools to interpret and communicate complex information effectively. They bridge the gap between raw data and human cognition, enabling individuals from diverse backgrounds to grasp insights quickly. However, a significant portion of the population feels unprepared to interpret these visual tools, which risks marginalizing non-expert audiences in critical conversations that rely on data evidence.

The importance of fostering literacy in data visualisation stems from the need to democratize access to information. When individuals can interpret graphs, charts, and interactive displays critically, they become active participants in societal debates concerning public health, climate change, economic policies, and more. Visual literacy promotes transparency and accountability because stakeholders can scrutinize data representations and challenge misleading or oversimplified narratives.

In the activity described, participants are asked to engage with visualisations by examining various types, including static and interactive formats. This exercise demonstrates the subjective nature of visual interpretation and emphasizes the importance of critical evaluation. By rating visualisations based on their liking and informativeness, users reveal their preferences and perceived clarity or effectiveness. Comparing responses fosters a collective understanding of what features make a visualisation impactful, such as clarity, aesthetics, accuracy, or interactivity.

Choosing visualisations that convey data effectively depends on several design principles. Clear axis labels, appropriate data scaling, and minimal clutter enhance comprehension. Interactive features like filtering or tooltips can deepen understanding but risk overwhelming users if not well-executed. For example, a pie chart with too many segments can be confusing, whereas a well-designed line graph can succinctly show trends over time. To improve visualisations, creators should prioritize simplicity, focus on key messages, and consider the target audience's level of data literacy.

Increasing the public’s capacity to interpret data visualisations aligns with broader goals of promoting informed citizenship. Educational initiatives, design best practices, and accessible technology are essential tools for this purpose. As data continues to influence policies and personal decisions, ensuring that visualisations are understandable and trustworthy is fundamental. This shared understanding empowers individuals to participate meaningfully in societal discussions, fostering transparency, and enhancing collective decision-making processes.
