They improved the visual experience by replacing the default gradient background on nodes with a solid fill color, reducing visual noise and creating a more cohesive appearance.

All changes were consolidated into a single feature commit for easier traceability and review. The work demonstrated proficiency in React, JavaScript, and data visualization, with a targeted, incremental engineering approach.
