Exploration of Temporal Hierarchical Layouts for Large Datasets
Problem
When working with large datasets, an option for providing an overview of the data is to group the objects hierarchically. However, this might lead to scalability issues when the dataset contains many attributes (= hierarchy levels) and/or many categories within an attribute (= many different groups per hierarchy level). Additionally, the group membership of objects might change over time.
We will use the Database of Modern Exhibitions (DoME) [1], which contains more than 13.000 artists, 13 attributes per artist, up to 38 categories per attribute, and 11 years, to form the hierarchy. Our goal is to explore the following two types of layouts and analyze their scalability.
1) Sunburst Diagrams [2, 3], a radial hierarchy that starts at the center and expands outwards (also possible with temporal aspects).
2) Fractal Trees [4], a tree hierarchy with branches for different hierarchy levels and the option to display timelines as "leaves".
Aim
The aim is to develop an interactive, web-based, deployable visualization that addresses one of the topics above, for example, using D3.js and React.
