Data Visualization Iteration
A major challenge was developing a system to accurately compare various datasets across different groups such as class subjects, grade years, and demographics like race, gender, and fiscal status. We also needed functionality to toggle between graphs comparing data for the current year and those comparing this year to the previous one. Additionally, the client required that multi-variable comparisons between demographics, such as race and gender, be avoided. To address this, we used tabs to distinguish between data that could be compared and data that could not. This solution, refined through multiple iterations of testing and client feedback, resulted in an effective system for managing and comparing the data, as illustrated in the figures below.

The end result of this iterative process was the implementation of a thermometer-style graph and a data table for comparing data within a single school year. For multi-year comparisons, we utilized two line graphs that allowed users to hover over specific lines to gain more insights into data comparisons. This design not only made the information visually engaging but also provided users with interactive elements to explore the data in greater detail.
