Citation Network

An interactive citation graph mapping how closely AI-explanation research and design’s comprehension research actually cite each other — turning a bibliometric pattern into something you can see and explore, rather than just state.

Hi, I'm Juliana.

I'm a product and data visualization designer specializing in UX for power users working with complex, high-volume data—designing dashboards, analytics tools, and decision-support systems grounded in research and analysis.

Clients include Goldman Sachs, JPMorgan Chase, Morgan Stanley, and ADP.

This site is a space for personal explorations, where I treat code as a design medium, using AI-assisted tools to rapidly explore interaction patterns, data representations, and system behaviors—particularly in the context of explainable AI and model-informed decision-making.
