Description
The aspect ratio of a data visualization affects how quickly users can detect trends and patterns in a data visualization. The aspect ratio is critical when plotting time series data. In line charts, trends are judged based on the slope of plotted lines, which are greatly affected by the aspect ratio of the graph. Line angles and slope guide the user when exploring data in parallel coordinates. The effect on the interpretability of line angles in parallel coordinates under different aspect ratios has yet to be studied.
Tasks
The project involves the following tasks:
- Design a user study.
- Implement a web-based framework for conducting the user study.
- Conduct a web-based user study with approx. 20 participants.
- Interpret the results.
Requirements
- Knowledge of web based APIs.
- Basic knowledge about data visualization.
Environment
The project should be implemented as a web-based application.
