Data visualization dashboard


Select a complex domain and conduct a literature review of current data visualization strategies within the space. Propose a redesign of an interactive data visualization solution to support expert users.


I chose to work with version control data generated by software developers.

Literature review and hypothesis

Based on my literature review, I came up with the hypothesis that current design solutions overcomplicate version control information. If I could design a simpler solution for visualizing version control data, I could make developer’s jobs a little easier. Additionally, the visualization could help non-expert users better understand what it is software developers do and how they work.

Design process

  • I started by writing a script to pull data from the Github API. I wanted to play around with real data so that my prototype felt authentic as possible

  • Simultaneously, I worked on thumbnail sketches of possible visualization solutions. This was how I landed on the stacked area graph design

  • Next, I built a static prototype to figure out how I wanted to lay out my dashboard

  • Finally, I built a working proof-of-concept using the Tableau data visualization software

Next steps

Further research is needed to validate my design solutions and provide feedback for future iterations. For the remainder of the year, I will conduct research in this domain space as part of my master’s thesis. Stay tuned!
