BALKAN FamilyTree JS is a comprehensive JavaScript library specifically developed for software engineers to create dynamic and interactive family tree applications. Often referred to as genealogy or pedigree charts, these applications visually represent complex family relationships in a conventional tree structure. This library simplifies the development process by providing a robust set of tools and functionalities, allowing developers to focus on application logic rather than intricate UI rendering. It addresses the challenge of visualizing large and complex datasets of familial connections, offering features that enhance user interaction and data management within the family tree interface. Users can interact with the tree through features like zooming, expanding/collapsing nodes, and navigating with scroll bars or a mini-map. The library supports various display and interaction options, including different orientations and the ability to handle multiple partners for individuals. Developers can customize nodes, implement search and filter functionalities, and manage multi-connections. Data can be imported and exported in various formats such as PDF, PNG, SVG, XML, and JSON, ensuring data portability. Advanced features like undo/redo, lazy loading for performance, and customizable menus and edit forms further enhance the development experience, making it suitable for diverse genealogical projects and applications.
