Syllabus

Course Introduction

Building on foundational concepts, this course delves into advanced visualization techniques, including the use of color, interactivity, and different visualization types such as network and map visualizations. Learners will also gain practical experience with popular data visualization tools.

Color

This module explores the role of color in data visualization, covering how color affects perception and communication. Learners will study color perception, psychological effects, and the theory behind primary colors. It will also cover additive and subtractive color mixing, color spaces like RGB, HLS, CIE, YUV, and Lab, and converting images between color spaces. Through practical exercises, learners will gain skills to choose colors that improve the clarity and impact of their visual data presentations.

Interaction

This module focuses on interactive visualization, highlighting how user engagement enhances data interpretation and decision-making. Learners will explore various user interactions, from hover effects to dynamic filtering, and understand the taxonomy of interactions and their impact on data exploration. The module covers selection methods for highlighting, selecting, and manipulating data points. Through practical applications and case studies, learners will gain skills to create interactive visualizations that boost user engagement and improve data storytelling.

Hierarchical and Network Visualization

This module explores trees, graphs, and network visualization, focusing on both theory and practice for representing complex data relationships. Learners will study network theory and different types of graphs (directed, undirected, weighted, and unweighted) and their applications. The module also covers visualization techniques like node-link diagrams, adjacency matrices, and hierarchical visualizations. Through hands-on exercises and case studies, learners will develop skills to create visualizations that clearly communicate the structure and dynamics of complex networks, improving their ability to analyze relational data.

Maps and Visualization

This module focuses on maps and cartography visualization, highlighting the role of geospatial representation in understanding complex data. Learners will explore how to transform spatial data into effective visual formats and study common geospatial visualizations such as thematic maps, heat maps, and interactive web maps. The module covers the benefits and trade-offs of different map types, helping learners select the best visualization methods for specific data and audiences. Through practical exercises and case studies, this module equips learners with the skills to create impactful maps that enhance spatial analysis and decision-making.

Text Visualization

This module covers the challenges and opportunities of visualizing unstructured data and textual documents. Learners will explore the complexities of representing textual information and the use of word clouds, discussing their benefits and limitations. The module also examines techniques to summarize documents, highlight key content, and track changes over time. Through hands-on activities and case studies, learners will gain the skills to effectively visualize text data, improving comprehension and communication of information from textual sources.
