Advanced Techniques in Data Visualization

When your data includes networks, hierarchies, maps, or unstructured text, you’ve outgrown the default tools. The story you need to tell with your data is more nuanced.

Dr. Jesus Caban’s second course in the Certificate in Data Visualization teaches you to turn visualizations into thinking tools that don’t just summarize—they reveal. The learning experience combines videos readings hands on activities, and quizzes to keep you building and applying knowledge.

You’ll begin by examining the role of color in perception and communication. With RGB and CIELab color spaces and tools like ColorBrewer, select palettes that enhance clarity, emphasize meaning, and support accessibility.

With dynamic features like zooming, filtering, brushing, tooltips, and semantic zooming, use interaction to support exploration and context-aware storytelling—and keep them responsive. Now users (and you as the designer) can spot patterns and draw conclusions without clutter.

Tackle networks and hierarchies like social networks, organizational structures, and systems design, with node-link diagrams, treemaps, clustering layouts, and edge bundlind.

Explore geospatial visualization, using maps, projections, and flow diagrams to uncover regional trends, disparities, and relationships—so geography can clarify your learnings instead of distorting them.

As written content becomes more central to research and decision-making, word clouds and document comparison techniques help you surface patterns, sentiment, and key themes—turning language into insight, even at scale.

By the end of this course, you’ll be equipped to handle visualization challenges in most real-world projects. You’ll have a strong, flexible toolkit and the judgment to use it well.

Use the platform you’re most comfortable with. The concepts apply equally to Tableau, Power BI, Python, or any other tool.
