Data Visualization

Course Rationale

 

Today quantitative and symbolic data are easily collected in computer format, from databases, websites, smartdevices, and anything that has interconnect capabilities. When such large amounts of data are put in spreadsheets or tabular reports, it becomes dicult to see the patterns, structure, trends, or relationships inherent in the data. Eective data visualization exposes these inherent relationships, consolidating and illustrating them in graphics.

 

Course Description

 

A visualization organizes data in a way that the structure and relationships in the data that may not be so easily understood becomes easily understood and interpreted with the visualization. Visualizations of a data set give the reader a narrative that tells the story of the data.

The purpose of data visualization is to convey information contained in data to clearly and eciently communicate an accurate picture of what the data says through understandable and context appropriate visualizations.

To do a visualization can be just exploratory or entails using Machine

Learning techniques that determine the structure of the data. The visualizations are then matched to the data structure.

The course will explore how principles of information graphics and design and how principles of visual perception, can be used with machine learning techniques to make eective data visualizations.

Each student will make a presentation of some principles of data visualizations or do a visualization project.

The course is open to PhD students in all programs. Non-computer science students will be paired with computer science students for the visualization project.
