Data Visualization Proficiency

  • 30m
  • 20 questions
The Data Visualization Proficiency benchmark will measure your ability to recall, relate, demonstrate, and apply the data visualization concepts and techniques in Excel, QlikView, and various Python visualization libraries. You will be evaluated on your ability to recognize and apply the concepts of data visualization techniques, tools, and functions in Excel, Qlikview, Infographics, and Python. A learner who scores high on this benchmark demonstrates that they have the required data visualization skills to understand, apply, and work independently on the visualizations in their projects.

Topics covered

  • configure elements such as text and icons to create an infographic
