This visualization explores the multiple choice question concerning the organization area where the people are working in.
First, the absolute frequencies for each area is shown. An important part is covered by Private sector and Information Technology, whereas Journalism and Marketing rank the bottom of the list despite being areas where visuals are important. I think this distribution doesn't represent the population at all and it's only valid for the survey frame.
Second, I focus in the nature of the multiple choices. The distribution of the number of choices and a clustering according to the combinations in the survey. This latter reveals two groups: one concerning business and another related to social aspects. This means that there is some kind of polarization of the respondents and not only for who chose multiple areas. A strong relation between Private sector and Information Technology is also visible.
Third, a network plot is built where respondents are connected each other if they share the same area. As expected, groups for each organization area are formed, more or less discernible. The respondents who chose more than one area tend to go out from the regions that define each group. As result, a central cluster appears for the multiple choice respondents. This plot attempts to show the respondents relations and the multiple choice effects. For example, the Marketing group is almost completely merged because many answers for Marketing are included in a multiple choice.
Fourth and last, a statistical significant difference between single and multiple choices is detected: the respondents who chose multiple areas tend to work in smaller companies. Other differences are detected if we look at the departments where the people work for, or the modes of visualization used. Although they are statistical significant the percentage differences are smaller and less conclusive.
