Project 1 is a visualization implementation on Chicago demographics datasets (Age and Gender as well as Race and Origin). On this page, we will describe both how to use the application and what things can be accomplished with the application that I built. Below, we describe how to use the application.
To run the application, simply click on the link "Run Application" back in the homepage and it will direct you to the start of the application. Here, you will find a labeled map of the 77 communities of chicago as well as the districts identified by the appropriate colors.
Beneath the map, you will find three buttons, "Age and Gender", "Race", and "Origin". A description of each is described below.
This button will produce 12 different visualizations as you can see in the image above. Actually, there are three groups of visualizations, such that you can compare any three communities or districts, or even Chicago as a whole. In each group, you will find at the top, pie charts describing the age distribution by gender. This enables you to quickly compare the age distribution among men versus women within a specific area. The next visualization is a stacked bar chart, which enables you to not only determine the age distribution as a total of the population, but also breaks down by the number of men and women. This can provide some insight into a rough estimate of the ratio of men and women within a specific area and age. The final visualization is just a simple table of the actual data, which can also be helpful if a user would like to refer to the actual data points.
In the above paragraph, we described a single group of four visualizations. Of course, there are three such groups, so that a user can not only gain insight within a specific district, community, or Chicago as a whole, but compare that to other areas as well. Note that to change the area, you will find the drop down menu at the top of each group, which lists "Chicago" for data on the entire city of Chicago, a district (signified by "District" in the drop down menu), or finally a community.
This button will produce 9 different visualizations as you can see in the image above. Again, there are three groups for the purpose of comparing three different areas of Chicago for the demographics information. In each group, the user will find at the top, a pie chart that describes the number of people of each of seven races (white, black, American Indian, Asian, Pacific Islander (including Hawaii), people that identify themselves as a single race not already mentioned, or finally, people who describe themselves as at least two different races not already mentioned). Not only can the user determine the number of people of each race, but the pie chart provides a nice view of the proportions of the total of each race as well. The next visualization is the bar chart, which again displays the race distribution and finally, the user will find the raw data in a tabular format.
This button will produce 9 different visualizations and the description is essentially the same as that for the Race mode. The one key difference however, is that rather than visualizations describing race distribution, here we are concerned with the distribution of the place of origin for the people of Chicago.
As one can see, the user contains three modes, "Age and Gender", "Race", and "Origin". Each mode generates three groups of visualizations, each of which can display different districts, communities, or Chicago as a whole. In conclusion, we list the features in a list below.
