Updated GeoJSON output path to support better spatial data visualization. Commits: 1aa44c7a9b645f090df88998ccec26e6c33a2396; 6fd09a05e791e3cf00d8521340011fac424341b0. - Added Symbolic Linking Option in Spatial Data Conversion: Adds a linking option to create symbolic links to original SpatialData objects instead of copying them, reducing redundancy and potential data inconsistency and improving data management flexibility. Commit: 239726dffe6c79a2671eaa6d97acad68ce270a8c. Major bugs fixed: - Stabilized EditableGeoJsonLayer interactions with a temporary workaround to ensure reliable click handling and interaction in GeoJSON visualizations. - Avoided unintended GeoJSON output to the spatial path and refined genes panel layout by using absolute positioning to prevent UI glitches. Overall impact and accomplishments: - Improved reliability and usability of spatial data visualization, enabling faster data exploration and more robust dashboards. - Reduced data redundancy and improved data governance through symbolic linking, enabling safer data management and more flexible pipelines. - Business value realized: faster iteration on geospatial features, fewer user-reported issues, and clearer data relationships across spatial datasets. Technologies/skills demonstrated: - Front-end visualization robustness with Mapbox/GeoJSON integration, improved UI/UX design (layout, opacity, color). - Scripting for data conversion and file-system-level data management (symbolic linking).
