Find an example of an augmented scatterplot and click on the image. You can answer the following questions using either the default variables and cases, or else use the menu on the left to select variables and cases you are more interested in.

(a) Take a screenshot of the visualization (use the most recent year if multiple years are available) and include it.

(b) Which variable is displayed on the x-axis? The y-axis? The color of the points? The size of the points?

(c) Describe what you see in this static visualization. (You don't have to describe everything, just choose a few of the most obvious or interesting features.)

(d) Choose one point and hover over it to see which country (or case) it corresponds to. Give the values of each variable for this country (or case).

(e) If this is a dynamic graph, press play to watch the trend over time. Comment on what is happening over time.

(f) If this is a dynamic graph, choose one case, identify its name, and explain how this case changes over time.

The link http://www.google.com/publicdata/directory brings up some data visualizations created from public online data. Hovering your mouse over the little circles below the visualization brings you to a different data visualization (or you can just wait for the image to change). Many of the visualizations are dynamic, and by clicking them and then pressing the play button, you can watch them change over time. Also, when you click on the image, you can then edit it, including changing the variables and cases (often countries) displayed, or even the way the data are visualized. You can also hover over the points to see case labels and get more accurate information.
