Background:  Applying the material covered in Chapter 6 and now in Chapter 7  specifically focusing on Interactivity, the assignment for this chapter  will analyze the gallery of 49 chart types from Chapter 6 and provide  the following for 5 of your choice.

1.  Select 5 chart type options from the gallery of 49 presented in Chapter 6

2.  For  each, select 3 of the 5 most often used data adjustment features and  for each describe in detail how you would apply each to each of the 5  chart types. Example for one: Chart Type Selected – Word Cloud.  The 3  Data Adjustments selected: Contributing – force input from the  viewer/user to select one word from a drop-down list before moving  forward with the display. The results would display the visualization  with the stats for the word the viewer/user selected.  The format for  this information should be in a table format with no attempt for full  sentences.

3.  Immediately  following this table, provide your perspective related to any problems,  issues or constraints in selecting 3 data adjustment features for each  chart type selected. You do not have to use the same data adjustment  features for each chart type.  An example of issues could be after  selecting a Stream Graph and a Framing data adjustment feature, any  example I developed did not make sense.  I also had to change the data  adjustment feature of navigating as my first choice because I could not  think of an example to fit the data and chart type.   Do NOT use any  suggestion if any is provided in the text for interactivity.  Do not  copy my examples. You must not copy and paste any information from the  text from the pages in the gallery.  You must apply what you have  learned from the previous chapters and not copy and paste from other  sources.  When you do use other sources to help gather any knowledge  such as the text and other online materials such as the book companion  site or the library, include each as a source on the reference page  following APA formatting.

4.  For  each chart type selected, provide examples for each of the 3  Presentation adjustments and why those examples fit the data and chart  type.  Again, use a table format instead of attempting sentences.

5.  Immediately  following this table, provide your perspective related to any problems,  issues or constraints in developing the examples of the 3 Presentation  adjustments for each chart type selected. An example could be after  selecting a Waffle Chart and a Focusing presentation adjustment feature,  I had to develop 4 examples before the final choice made sense.  Do NOT  use any suggestion if any is provided in the text for interactivity. Do  not copy any example I provided.  You must not copy and paste any  information from the text from the pages in the gallery.  You must apply  what you have learned from the previous chapters and not copy and paste  from other sources.  When you do use other sources to help gather any  knowledge such as the text and other online materials such as the book  companion site or the library, include each as a source on the reference  page following APA formatting.

6.  In  a conclusion, provide your reflection on the chapter contents, the  material and discussions in the discussion forum, and the efforts to  complete the above requirements to include how these activities and  knowledge will assist you in the future for your data visualization  projects.  These future projects could be the possible initiations at  your organization or personal effort or maybe an upcoming class or  degree requirement.

Your  research paper should be at least 3 pages (800 words), double-spaced,  margins are normal, have at least 4 APA references, and typed in an  easy-to-read consistent font family (size no lager than 12) in MS Word  (other word processors are fine to use but save it in MS Word format).  Your cover page should contain the following: Title, Student’s name,  University’s name, Course name, Course number, Professor’s name, and  Date.

You will be asked to fill various needs within an organization. Troubleshooting is not like throwing darts. It is a methodical process based on what you know about computer issues and behaviors. Please answer all of the following issues.

1. My computer made a screaming noise like a girl on a rollercoaster. Now it will not turn on. What happed to the computer? Was that its death scream? Do all computers do this after a year of use? What are possible causes? How will you address the issue?
2. I was about to shut down this computer yesterday, an error popped out “There is another user logging onto this computer. If you shut it down will cause them to lose data.” I’m afraid to shutdown my computer because someone else is using it. Who is on my computer? How do you handle this request?
3. One of your clients brings their laptop to you and says it seems really hot on the bottom. Explain some of the possible causes. How do you handle this request?
