Yohan Durand developed advanced data-driven visualization components for the OpenRailAssociation/osrd-ui repository, focusing on the Track Occupancy Diagram and Spacetime Chart. He architected modular React and TypeScript components that render real-time train occupancy, time captions, and multi-train scenarios, integrating Storybook for isolated UI testing and maintainability. His work included scalable Canvas API rendering, targeted bug fixes to improve chart redraw reliability, and UI asset cleanup to reduce bundle size. By emphasizing component integration, maintainable CSS, and robust data wiring, Yohan enabled faster validation cycles and laid a solid foundation for future extensibility in complex railway scheduling interfaces.

March 2025 performance summary for OpenRailAssociation/osrd-ui: Delivered UI asset cleanup with the TrackOccupancyCanvas component, removing obsolete font imports and binary font assets in ui-charts; this reduces asset bloat, simplifies maintenance, and aligns with ongoing UI refactors. No major bugs fixed this month; focus on code quality and maintainability. Technologies demonstrated include React/TypeScript component cleanup, storybook asset management, and disciplined version-control practices, setting the stage for further UI refinements.

Month 2025-02: Focused stabilization of the Spacetime Chart in OpenRailAssociation/osrd-ui. Delivered a targeted frontend bug fix that ensures the spacetime chart's op graduation display updates correctly when certain operational points are hidden, and that any changes driven by machette settings trigger a redraw. This improves visual consistency and reliability of critical monitoring dashboards. Commit reference is traceable for this work. Impact: reduces visual drift, minimizes manual refresh needs, and enhances user trust in real-time visualization.

December 2024 performance summary for OpenRailAssociation/osrd-ui. Delivered a major UI enhancement to the Track Occupancy Diagram, introducing through-train visualization and multi-train rendering, along with a selected-train highlight. Styling and maintainability improvements were completed in parallel (style.css, mockup color names) to support future iterations and Storybook/story assets. No major bugs fixed this month; primary focus was feature delivery, code quality, and establishing a solid foundation for extended data-driven visualization.

Month: 2024-11 | Repository: OpenRailAssociation/osrd-ui. Focused on delivering foundational Track Occupancy Diagram visuals and establishing a scalable, data-driven diagram architecture. Key features delivered include a baseline TrackOccupancyDiagram with core rendering and Storybook integration, a Time Captions Layer to display time-related information, and an Occupancy Zones Layer showing arrival/departure times, origin/destination, and train names. While no explicit bug fixes are listed in the provided data, initial rendering stability and data wiring were addressed to enable reliable visualization. This work improves stakeholder visibility into track occupancy and scheduling, enabling faster validation and iteration. Note: No major bugs fixed were recorded in the supplied data; the emphasis was on feature delivery and scaffolding that reduces future rework.
