Data visualization is the process of transforming data into visual elements, such as shapes, colors, sizes, or patterns, to reveal patterns, trends, outliers, or relationships. It can help simplify and organize data, highlight key insights, and tell a story. The Gestalt principles of perception explain how humans perceive and group visual elements based on similarity, proximity, continuity, closure, and symmetry. Additionally, the data-ink ratio suggests that the amount of ink used to display data should be maximized while non-data elements should be minimized. Lastly, the visual encoding refers to the choice of visual elements and attributes to represent data. It should match the type and scale of the data and avoid misleading or confusing the audience.

It's also as important to consider the following principles as they can greatly impact how people read data visualizations. Visual Hierarchy: Establishing a clear visual hierarchy helps users understand the importance and relationship between different elements in an information graphic. Elements like size, color, and typography can be used to create a hierarchy and guide the viewer's attention. Cognitive Load Theory: Cognitive load theory suggests that information should be presented in a way that minimizes cognitive effort and maximizes understanding. Designers aim to reduce extraneous cognitive load by simplifying complex concepts, utilizing clear visual cues, and presenting data in a logical order with the least amount of ink.
Information design is the process of organizing, structuring, and presenting information in a way that is clear, accessible, and understandable for the intended audience. It can help define the purpose and scope of a message, select and prioritize the most relevant and meaningful information, and arrange and format it in a logical and consistent way. The information hierarchy is the order and importance of the information elements, such as the title, subtitle, introduction, body, conclusion, and sources. It should guide the audience's attention and comprehension to reflect the main message and goal of an infographic. The information architecture is the structure and organization of the information elements, such as the layout, navigation, labels, categories, and links. It should facilitate scanning, browsing, and exploring while providing clear paths and cues. The information aesthetics is the visual appearance and style of the elements like fonts, colors, images, icons, and graphics. It should enhance readability while conveying tone and mood.

In order to achieve this goal, it is important to understand the principles of design, which are the basic guidelines for creating a balanced and harmonious composition. This includes elements such as contrast, alignment, repetition, proximity, hierarchy, and whitespace. Additionally, the elements of design should be used strategically to create contrast, harmony, emphasis, movement, rhythm or unity. Moreover, it is essential to understand the color theory in order to create a color scheme that matches the theme and mood of your infographic. This theory includes hues, saturation, value, temperature complementarity contrast and harmony. By applying these principles and theories to your infographics you can create engaging visuals that are informative and accurate.
