Worked on the tier4_perception_dataset repository to enhance the clarity and consistency of project diagrams by implementing a white background for Draw.io SVG files. This update addressed rendering inconsistencies across browsers, embedded images, and raster exports, ensuring that visuals remain readable and aligned with project documentation and the nuscenes schema. The solution combined style-based backgrounds with explicit background rectangles, improving onboarding and data interpretation for stakeholders. All changes were documented in a single, traceable commit, with updates to both the SVG diagrams and related documentation. The work utilized SVG rendering, data visualization techniques, and documentation skills, primarily using Markdown and YAML.
