- _
Using Heatmap
01:28:37 - 01:45:35
Using Heatmap
Shirley demonstrates how to generate heatmaps with Vega-Lite displaying the release date and genre of blockbuster movies.
Exploration Exercise
01:45:36 - 01:50:25
Exploration Exercise
Shirley reviews the methods that she went through to explore the data that the audience had previously done, and the thought process throughout. The audience is asked to jot down a few points they though were interesting, and things they think are important to keep in mind when exploring datasets. Further advice is given when exploring a dataset. - _
Design
Marks & Channels
01:50:26 - 02:12:29
Marks & Channels
Once a question or hypothesis is answered, or something interesting is found, Shirley suggests to build a story around that theme thinking through how to translate that story into visual encodings.In this section, the design of the visualization is also introduced. Shirley explains what marks and channels are, how they differ, and then introduces the impacts of the various channels. Within this section, Tamara Munzer's Visualization Analysis and Design is referenced as the inspiration for many of Shirley's points. - - _

Gestalt Laws of Grouping
02:12:30 - 02:17:14
Gestalt Laws of Grouping
Shirley covers the Gestalt principles of proximity, similarity, and exclosure that help explain how to utilize how the brain processes patterns for designing data visualizations. - _
Remix & Overlay
02:17:15 - 02:18:24
Remix & Overlay
Shirley urges gaining inspiration from work that has done before rather than attempting to start from scratch.
Design Exercise
02:18:25 - 02:20:23

Interactions
04:09:52 - 04:12:23
