4. Good and Bad Data Visualizations
An important skill is the ability to critically evaluate information. As our world is increasingly filled with data, more and more the information from that data is conveyed through visualizations.
Visualization is useful for both discovery of connections and trends and also communication - both are potentially aspects of the Explore Performance Task. In this lesson we will focus on the communication aspects of visualization.

5. Good and Bad Data Visualizations
Interpreting data visualizations is not typically thought of as a core computer science skill, but it is certainly an important one in an age of digital data. Computing has enabled massive amounts of information to be automatically collected, aggregated, analyzed, and visualized.

6. Good and Bad Data Visualizations
Visualizations are useful in helping humans understand large amounts of data quickly, and they are useful communication tools when presenting findings about a collection of data.
Not all visualizations are created equal, however, and in many cases the type of visualization used may distract or even mislead the reader.

7. Good and Bad Data Visualizations
As both creators and consumers of data visualizations, students need to be on the lookout for these common pitfalls. This will allow them to be savvier readers of data visualizations, and more effective communicators when creating visualizations of their own
