ITHS Data Visualizations CSE 512 Final Project
Jacob Olsufka, Ross Lordon, Ahmad Aljadaan
In this project we created three prototype data visualizations for the UW ITHS Data QUEST team. The Data QUEST team has an immediate need for improved data visualization and interactions on their website. In light of this, we opted to develop three different visualization prototypes. The purpose of each is to allow researchers to quickly and effectively explore the data, while influencing potential research questions or projects.
Small Multiples
One visualization method we pursued consisted of a small multiple approach to compare between clinics using bar charts. The purpose of this visualization is to allow researchers the ability quickly assess the demographics of all the clinics combined and for each individual clinic selected for analysis. The demographics included in the prototype are gender, race, ethnicity, and age. One larger multiple is displayed on the left hand side depicting the total for all the clinics currently being analyzed to the right of the larger multiple are the smaller multiples depicting the breakdown of the smaller clinics. Mouse over is incorporated into each bar in each chart to provide details on demand to the user.

Force Bubble Diagram
The force bubble diagram allows the user to explore the breadth and depth of the data in regards to the patients’ demographics. The purpose is to facilitate exploratory data analysis in a fun and engaging experience. It is our hope that this tool creates increased interest from a researcher looking to learn more about the dataset available. This interactive chart allows for two simultaneous user inputs for analysis. First, the bubbles can be sorted by the same demographic categories listed above for the small multiples visualization. Second, the user can color the dots to depict the distribution of a second demographic variable within the clusters of the first demographic variable selected. The size of the bubbles represents the longevity of each patient’s time seen at the clinic. Details on demand are provided to the user through mouse over.

Stacked Bar Chart
The stacked bar chart visualization allows the user to navigate the clinical data for specific disease for different years. This display allows the user to navigate through the aggregate data by number of patients. This is accomplished by selecting from the same demographic options used in the previous examples. Users may find patterns that occurred during a specific time frame for a certain demographic diagnosed with a specific disease. For example, if a user wanted to see if more males than females were diagnosed with depression from 2012-2014, this visualization could help researchers answer the question.
