Contributed to the NewsAppsUMD/maryland_voter_data repository by developing end-to-end analytics and visualization features for Maryland voter data. Built a demographic data processing suite that reshaped and visualized voter information by age, gender, and party, using Python, pandas, and Plotly to generate both static and interactive charts. Enhanced the frontend by upgrading JavaScript dependencies and build tooling, improving maintainability and visualization capabilities. Delivered a comprehensive voter turnout visualization suite for the 2020 and 2024 elections, including detailed breakdowns and interactive summaries. Focused on code organization, reusable components, and documentation to support scalable, data-driven reporting and future analytics enhancements.

May 1, 2025May 2025 monthly summary for NewsAppsUMD/maryland_voter_data: Delivered a comprehensive voter turnout visualization suite for the 2020 and 2024 elections, including age group, gender, and party breakdowns, with separate visuals for unaffiliated voters and enhanced hover/percentage summaries. Resolved chart title inconsistencies and refined the three combined charts to ensure accurate, consistent labeling across demographics. The work leveraged Python-based visualizations to produce interactive insights, supporting data-driven analysis of participation trends and informing stakeholders about turnout dynamics in key electoral cycles. This foundation enables scalable analytics for future election data reviews and reporting.

Apr 1, 2025April 2025 delivered a cohesive data-to-insight sequence for NewsAppsUMD/maryland_voter_data, focusing on API testing, demographic analytics, and frontend tooling upgrades. The Datawrapper API Test Tooling feature adds a dedicated test_script.py to exercise the Datawrapper API, validates authentication via the DATAWRAPPER_MD_DATA environment variable, reorganizes tests into a dedicated directory, and lays groundwork for pandas-based data manipulation to support future testing. The Demographic Data Processing and Visualization Suite introduces end-to-end analytics: reshaping voter data by age, gender, and party, and generating both static and interactive visualizations (bar charts and per-age-group metrics) using pandas, matplotlib, seaborn, and Plotly. The Frontend Dependency Upgrade and Tooling Refresh modernizes the JS stack and build tooling (svg-arc-to-cubic-bezier, supports-color, string-width, terser-webpack-plugin) and adds libraries such as string-split-by and strongly-connected-components to broaden visualization capabilities. Minor chart title fixes improve accuracy and consistency across visuals. Collectively, these efforts raise data quality, reduce manual testing effort, accelerate reporting cycles, and strengthen the platform's ability to deliver actionable demographics insights for stakeholders.
