Specialized Data Visualization Approaches

Not all data fits neatly into a table or a dashboard. In fields like healthcare, engineering, environmental science, and cybersecurity, the data is often multi-dimensional, continuous, and dynamic.

Dr. Jesus Caban built the final course in his Certificate in Data Visualization for these scenarios—the moments when traditional charts fall short, and the real challenge is designing a visualization that can keep up with the complexity of the data itself.

The videos, readings and hands-on projects will prepare you with the techniques for working with these specialized data types—from volumetric scans and 3D models, to temporal patterns, vector fields, and multivariate time series. These aren’t just technical challenges—they’re visual and cognitive ones, too.

You’ll begin with temporal data—learning how to visualize change over time using techniques that go beyond basic timelines or line charts. You’ll explore how time interacts with other dimensions, how motion and animation can aid or obscure interpretation, and how to encode duration, frequency, and sequence in meaningful ways.

From there, you’ll move into the visual challenges of 3D and volumetric data—the kind used in medical imaging, simulation modeling, and geospatial analysis. You’ll work with techniques like raycasting and transfer functions to explore how volume, opacity, and perspective affect what the user sees—and what they miss. These aren’t just visual tricks; they’re essential tools for navigating data that exists in three dimensions.

Next, you’ll tackle vector and flow data, learning how to represent directional movement, density, and continuity in systems like weather models, blood flow, or traffic networks. You’ll consider the trade-offs of glyphs, streamlines, and particle traces—and how to design visuals that remain clear even as the data becomes more dynamic.

Throughout the course, you’ll return to a key question: How do I know this visualization works? You’ll explore methods for evaluating visualizations, including user feedback, heuristic analysis, and task-based testing—ensuring the techniques you apply are not only technically sound, but cognitively effective.

By the end of this course, you’ll be equipped to take on high-complexity, domain-specific data challenges—designing visualizations that reveal structure in space, change over time, and movement across systems. More importantly, you’ll have the judgment to know when a visualization works, why it works, and how to make it better.
