Derived Data:

  • total donations per donor per year - quantitative

  • donor continents - categorical
  • recipient continents - categorical
  • total donations per donor continent per year - quantitative

Abstract Tasks

Analyze > Consume > Present

Search > Lookup --> Query > Identify Extremes

  • donors with the largest donations
  • recipients with the largest donations

Search > Locate --> Identify > One

  • total donations from a particular country
  • total donations from a particular continent

Search > Explore --> Query > Summarize Distribution

  • donations per donor
  • donations per recipient

Search > Explore --> Query > Compare Dependency

  • links between donor country and recipient country
  • links between donor continent and recipient continent

Application to Project:

For each of the abstract tasks (except derive), there should be a chart that allows that task to be performed. It may be that a single chart can support multiple tasks. In your project report, you will describe which charts allow which tasks to be performed.
