- Early to Mid-Career Data Professionals: Individuals seeking to move beyond tables and charts to create clear, meaningful visual stories.
- Analysts and Researchers: Professionals who regularly work with complex datasets and need to communicate their findings clearly and persuasively to various stakeholders.
- Designers and Communicators: Individuals interested in applying graphic design principles and human perception to create impactful, user-friendly Data Visualizations.
- Students and Academics: Those who wish to build a strong foundational understanding of Data Visualization techniques and their theoretical underpinnings.
What You Will Learn?
The curriculum is structured into four core modules, guiding learners from historical context to advanced design principles.
Module 1: Introduction to Data Visualization
Learners explore the foundations and historical evolution of visualization techniques. Key topics include:
- Identifying Misleading Visualizations.
- Role of Visualization in Simplifying Complex Data.
Module 2: Visualization Techniques
Learners explore techniques based on data type and evaluate basic charts and graphs. Key topics include:
- Strengths and Weaknesses of Hierarchical Visualizations and Scatter Plots.
- Choosing the Right Visualization for Tabular, Geospatial, and Scalar Data.
Module 3: Human Visual Perception
Learners uncover how perceptual principles inform effective information visualization. Key topics include:
- Influence of Visual Variables (Position, Color, Size).
- Applying Gestalt Principles and Grouping Techniques.
Module 4: Design Principles
Learners dive into the stages of the visual design process. Key topics include:
- Key Principles of Effective Design (Simplicity, Consistency, Organization).
- Understanding Graphical Excellence and Its Real-World Applications.
Analytical Assessments (Sample Projects)
To reinforce learning, participants complete hands-on analytical assessments. Examples include:
1. Spot the Flaw: Misleading Data in the Wild
Analyze deceptive charts to understand how visual choices like omitted axes or distorted scales can mislead audiences and erode trust.
2. Chart Smart: Building the Basics with the Iris Dataset
Create classic visualizations and practice the fundamentals of chart construction, labeling, and layout using the famous 1936 Iris flower dataset.
3. Visual Vocabulary: Designing with Encodings
Explore the power of position, color, size, and shape by creating custom visualizations with the "Tips" dataset to express patterns and comparisons more effectively.
4. Debt by Design: Critiquing a Complex Dashboard
Evaluate the U.S. Debt Clock dashboard through the lens of simplicity, structure, and graphical excellence to understand how overwhelming design choices can obscure meaning.
Key Learning Outcomes
By completing the program, learners will gain the ability to:
- Describe the foundations of human visual perception and explain how perceptual principles inform effective information visualization.
- Explain core visual design principles for creating clear and accurate representations of data.
- Analyze and evaluate visualization techniques, identifying their strengths, limitations, and potential for misleading representations.
- Differentiate among major data types, including tabular, hierarchical, geospatial, textual, and scalar, and explain appropriate visualization approaches for each.
- Identify established data visualization tools and environments within the broader field of information visualization.
Certification and Learning Ecosystem
Upon successful completion of the course, learners will earn a globally recognized Certificate of Completion and 2 Continuing Education Units (CEUs) from Johns Hopkins University.
The program is offered in collaboration with Great Learning, a leading global ed-tech company that has impacted 14 million+ learners from over 170 countries. Great Learning manages enrollments, payments, invoicing, and technology support for the course.
