February 2025 monthly summary for repository bokeh/bokeh. Key achievements focus on improving interactive UX and stabilizing rendering behavior for data visualizations. Delivered two main items: (1) BoxAnnotation Cursor Feedback Enhancement to communicate interactivity during drag/move operations, enabling precise and intuitive box selections; (2) Tooltip Hover Background Color Rendering Bug fix ensuring tooltip colors from the data source are correctly processed and applied as CSS colors, resolving a rendering inconsistency. Business value: enhances user productivity and confidence when exploring data visualizations, reduces support questions related to tooltip styling and interaction, and strengthens the reliability of interactive widgets. Technical impact: introduced a responsive cursor state during box interactions and corrected color processing flow in the hover example, with traceable commits for accountability and easier future audits.
