Worked on enhancing circuit simulation visualization in the phetsims/babel repository, focusing on improving data interpretation and interoperability for educators and researchers. Developed new features using JavaScript and front end development skills, including the addition of sensor and chart labels to simulation visuals and support for alternate sensors to broaden data compatibility. Integrated a CCK CODAP wrapper, enabling seamless data visualization and facilitating cross-tool analytics with external data analysis tools. The work addressed the need for richer, more accessible data displays within the simulation environment, with all changes traceable to a documented issue and commit for transparency and maintainability.
