A data team at a public university wants to communicate to stakeholders about which foreign language courses are most popular with students. They create a data visualization that identifies the 38 different courses, then shows the number of students enrolled in each one. What type of data visualization should they create?

Describe how you would create visualizations to display information that describes the following types of systems. Computer networks. Be sure to include both the static aspects of the network, such as connectivity, and the dynamic aspects, such as traffic. The distribution of specific plant and animal species around the world for a specific moment in time. The use of computer resources, such as processor time, main memory, and disk, for a set of benchmark database programs. The change in occupation of workers in a particular country over the last thirty years. Assume that you have yearly information about each person that also includes gender and level of education. What are the arrangement issues that arise with respect to three-dimensional plots? Discuss the advantages and disadvantages of using sampling to reduce the number of data objects that need to be displayed. Would simple random sampling (without replacement) be a good approach to sampling? Why or why not? Describe how a box plot can give information about whether the value of an attribute is symmetrically distributed. What can you say about the symmetry of the distributions of the attributes?

Understanding types of data visualisationSuppose you have to make a presentation to divide the budget for different departments namely sales, marketing and HR. Which of the following data visualisation tools would be most appropriate for the presentation?HistogramPie chartBar graphLine graph

The nature of the data: what do those data represent/describe? how were they originally collected? (This is not asking where 'you' obtained this dataset from.)Who are the typical consumers of such data?How are those data typically depicted or conveyed to those audiences? Present your explanation/argument with respect to data types.What sort of questions are asked and answered through such typical visualization you’ve mentioned in #3?What might be typical mistakes people make in depicting those data?How would YOU visualise those data differently? Using the symbolic representations from Semiology of Graphics, describe and explain how you would define the imposition of your visualisation, and how you would assign each data type to various visual variables.

Which of the following statements are true about using visualizations to display a dataset?I. Visualizations are visually appealing, but don’t help the viewer understand relationships that exist in the dataII. Visualizations like graphs, charts, or visualizations with pictures are useful for conveying information, while tables just filled with text are not useful.III. Patterns that exist in the data can be found more easily by using a visualizationI and IIII and IIIIII onlyI, II, and III
