Grad: Approx 1000 words total, 2 types per person

Visualization guide posts should be aimed at an audience of historians, and should aim to give a basic understanding of what each visualization is useful for to someone who understands basic line/bar/pie charts.

For each of your assigned chart types, your visualization guide should discuss:

  • What kind of data does this chart display well?
  • What kind of data is NOT suitable for this type of chart?
  • What kind of relationship or pattern can this chart illustrate? (eg, change over time, relationship between two quantitative measures, relationship between a quantitative and qualitative measure, etc)

Additionally, you should find and discuss an example of your chart type. You may use any of the resources assigned for the class, or other sources like 538, Mike Bostock’s NY Times articles, @nytimesgraphics, @PostGraphics, the Economist’s Graphic Detail blog, The Guardian Interactive, the D3.js example gallery, Flowing Data, Information is Beautiful, The Pudding, r/DataIsBeautiful, r/DataIsUgly, JunkCharts, WTF Visualizations, Include both a link and an attributed image of your example chart in your post.

Your post should be tagged with the “Visualization Guide” category.
