Open the Animals Starter File and click "Run".

Part A:

Test the following expressions in the Interactions Area:

  • count​(​animals-table, "species"​)

  • bar-chart​(​animals-table, "species"​)

1 How do they compare?

2 Which do you like better: the bar chart or the table? Why?

Now test out the expression pie-chart​(​animals-table, "species"​)

3 How does this pie chart compare to the bar chart you just made?

When you first build a bar chart or pie chart in pyret, they are interactive displays. That means that you can mouse over them for more information. Hit the up arrow in the interactions area to reload your last expression and test it out!

Part B:

4 Make a pie-chart and bar-chart for the pounds column. Why isn’t grouping the pounds column very useful?

5 Look at the list of columns in the Definitions Area. For which columns do you expect pie charts to be most useful?

Part C: (Best completed after Bar & Pie Chart - Notice and Wonder and Matching Bar and Pie Charts)

6 How is pie-chart similar to bar-chart?

7 How are pie-chart and bar-chart different?

8 When would you want to use one chart instead of another?

9 What information is provided in bar charts that is hidden in pie charts?

10 Why might this sometimes be problematic?
