Key Findings

  • 01A significant number of user tasks exist for tree visualizations, spanning diverse applications.
  • 02A novel, extended typology is effective for abstracting and categorizing these tree-specific tasks.
  • 03A curated dataset of abstracted tasks can serve as a valuable resource for designers and researchers.
02

Application

Design takeaway

Before designing a tree visualization, consult or create a comprehensive list of user tasks to ensure the design effectively supports intended user activities.

How to apply

When embarking on a design project involving tree structures, begin by identifying and documenting the core user tasks that the visualization needs to support.

Project actions

  • 01When researching existing designs, actively look for descriptions of what users are trying to achieve.
  • 02Consider creating a categorized list of user tasks for your own design project to guide your decisions.
03

Method & Evidence

AimHow can a curated dataset of abstracted user tasks inform the design and evaluation of tree visualizations?
MethodLiterature review and task abstraction
ProcedureResearchers reviewed existing literature on tree visualizations, extracted user tasks, and then abstracted these tasks using a novel, extended typology. This resulted in a dataset of over 200 abstracted tasks.
Sample200+ tasks
ContextInformation visualization, specifically tree visualizations across various domains.

Variables

IVTask abstraction methodology and curated task dataset
DVEffectiveness of tree visualization design and evaluation
CVType of tree visualization, domain of application
04

Strengths & Limitations

Strengths

  • +Systematic and comprehensive literature review.
  • +Development of a novel task typology extension.

Limitations

It can be challenging to identify all possible user tasks from existing literature alone; direct user research might be necessary.

Reliability & validity

The reliability of the task abstraction depends on the consistency of the researchers applying the typology. Validity is supported by the breadth of the literature reviewed and the systematic nature of the abstraction process.

Think critically

To what extent does a predefined task dataset limit the potential for novel or unexpected user interactions and design innovations?

05

Design Principles

"Design for specific, well-defined user tasks."

Understanding the specific tasks users aim to accomplish with tree visualizations is crucial for effective design. A curated dataset of these tasks allows designers to benchmark their solutions against established user needs and to identify gaps in current visualization techniques.

06

What This Means for Your Design

By collecting and organizing all the things people want to do with tree diagrams, designers can make better tree diagrams that actually help people.

How to use in your project

  • 1.Use the concept of task analysis to justify design choices and to inform your evaluation strategy.
  • 2.Reference the methodology for task abstraction as an example of how to systematically understand user needs.
