Data Visualization and Dashboard Storytelling

Module 01 Activity

Scenario

You have inherited a set of charts someone else built, and been asked whether they are any good.

What you build

A critique of five real charts, with the question each answers and a rewritten takeaway sentence for each.

Steps

  1. For each chart, write the single question it answers. Mark any that answer none, and any where a sentence would have done.
  2. Write the action each chart prompts. Mark any that prompt none, and decide whether that is legitimate context or a defect.
  3. List every decorative feature and say what the reader can do afterwards that they could not before. Delete anything that fails.
  4. Show one chart to three colleagues and ask them the questions it should answer. Record the answers, not their opinions.
  5. Rewrite each title as a takeaway sentence containing a figure.
  6. Say which of the five you would delete outright, and why.
