This study introduces a longitudinal approach to evaluate visualization tools, capturing the full data analysis journey from raw data to insights. It offers valuable observations for improving visual analytics tools and evaluation methods.

Area of Science:

  • Bioinformatics
  • Data Visualization
  • Human-Computer Interaction

Background:

  • Traditional evaluations of visualization tools focus on short-term usage in controlled settings.
  • These controlled studies often fail to capture the complexities of long-term, real-world data analysis.

Purpose of the Study:

  • To investigate the long-term usage of visualization tools in a bioinformatics context.
  • To capture the complete data analysis process, from raw data to insight generation.
  • To provide a deeper understanding of visual analytics and insight generation.

Main Methods:

  • A longitudinal study was conducted observing a bioinformatics data set analysis.
  • The study focused on the entire analytical workflow of a user.
  • Data collection captured the process from raw data to final insights.
