Worked on enhancing the FlowDraw repository by implementing support for Entity-Relationship diagrams, focusing on both visual and data-model improvements. Utilized React and Konva to refactor connection rendering into a dedicated ConnectionEndpoint component, enabling scalable handling of multiple connection types. Integrated new SVG elements and updated the sidebar to allow ER diagram visualization, while replacing placeholder endpoints with actual SVG images for improved clarity. Updated the data model to accurately store and retrieve connection types, ensuring visual fidelity and data integrity. Emphasized maintainability and extensibility by introducing ER-specific SVG generation and refining connection endpoint rendering using TypeScript and JavaScript.
