Annotation is a crucial component of a good dataviz. It can turn a boring graphic into an interesting and insightful way to convey information. Dataviz is often separated in two main types: exploratory and explanatory analysis. Annotation is used for the second type.

Our current attention span for looking at things online is, on average, less than five seconds. So if you can’t grab someone’s attention within five seconds, you’ve likely lost your viewer. Adding accurate annotation can greatly help to grab audience attention. Use keywords, shapes, colors and other visuals to help them go straight to the point.

Annotation is a general concept, and hundreds of different ways to annotate a chart exist, depending on the context.

What are effective ways to leverage annotation in data visualizations? Provide 3 examples of how you would effectively use annotation in a data visualization. Describe how you would use them to keep viewers’ attention.

Discussion Length (word count): At least 250 words

References: At least three peer-reviewed, scholarly journal references.

Assignment 2: Crime Control vs. Due Process
For many years, New York City suffered from very high rates of both violent and property crime. In 2001, the September 11 attack brought down the World Trade Center towers. Since then, there have been several attempted acts of terrorism as well.
In response to these difficult challenges, the New York Police Department (NYPD) implemented several new procedures, including:
Stop and frisk
“Mosque crawling” (undercover surveillance of city mosques)
Prepare a report in Microsoft Word that addresses the following points:
Describe the two programs listed above.
Analyze whether these programs have been effective. To do this, you will need to locate crime statistics for New York City and determine whether crime and terrorism have increased or decreased.
Discuss how these programs relate to the issue of crime control versus due process.
Explain how the presence of crime or the potential for terrorism might impact New York economically.
Recently, the stop-and-frisk program has been suspended by a federal judge. Do you agree with this decision? Explain your reasoning.

Discussion

 Do you believe that all data should be encrypted? Many computing professionals think this is a good idea. But a small number of computing experts feel that no data should be encrypted—that all data and software should be openly available to anyone who wants it. Explain your answer (whether you believe all data should or should not be encrypted). 

 

Internet Research – Wk 11

In this module, you learned that random numbers (or, at least, pseudorandom numbers) are essential in cryptography, but it is extremely difficult even for powerful hardware and software to generate them. Go online and conduct research on random number generators. What are the different uses of these tools besides cryptography? How do they work? Explain your answer using your own words in 2-3 paragraphs 

Include at least one quote from each of 3 different articles

 

Write an essay of at least five hundred words discussing the use of encryption to protect data at rest, in motion, and in use. 

Do not copy without providing proper attribution. This paper will be evaluated through SafeAssign. 

Write in essay format not in outline, bulleted, numbered or other list format.  

Use the five paragraph format. Each paragraph must have at least five sentences. Include 3 quotes with quotation marks and cited in-line and in a list of references. Include an interesting meaninful title.

Include at least one quote from each of 3 different articles. Use the Research Databases available from the Danforth Library, not Google.   Place the words you copied (do not alter or paraphrase the words) in quotation marks and cite in-line (as all work copied from another should be handled). The quotes should be full sentences (no more, less) and should be incorporated in your discussion (they do not replace your discussion) to illustrate or emphasize your ideas.
