Supported Diagram Types

yEd supports a variety of diagram types through its extensive palette of predefined symbols and shapes, enabling users to create diagrams manually via drag-and-drop operations or with semi-automated assistance. These include standard notations for modeling processes, systems, and structures, with palettes tailored to specific domains such as and . Flowcharts are a core diagram type in yEd, used for and visualizing workflows, decision points, and sequential steps. Users can construct them by dragging process nodes, decision diamonds, and connectors from the palette, as seen in examples of business workflows or algorithm representations. For instance, creating a simple flowchart involves placing start/end ovals, action rectangles, and arrow-edged lines to depict a basic approval process. Unified Modeling Language (UML) diagrams are fully supported, including class diagrams for object-oriented design, sequence diagrams for interaction flows, and diagrams for system requirements. These are built using dedicated UML palettes with symbols like classes, actors, and lifelines, facilitating and analysis. UML support allows for precise representation of relationships such as and associations in class diagrams. Business Process Model and Notation (BPMN) diagrams enable the creation of standardized business process models, incorporating elements like tasks, gateways, events, and pools. yEd's BPMN palette provides symbols compliant with BPMN 2.0, suitable for modeling operational workflows in enterprises. Use cases include diagramming or processes. Network diagrams are designed for IT infrastructure visualization, featuring symbols for routers, servers, switches, and cloud elements to map connections and topologies. These diagrams help in planning and documenting computer networks or system architectures. Mind maps and organization charts address hierarchical structures, with mind maps using radial layouts for brainstorming ideas and organization charts employing tree-like formats for corporate hierarchies. yEd's palettes include central topics, branches, and sub-branches for mind maps, while org charts use boxes and lines to show reporting lines. Entity-relationship (ER) diagrams support , with notations like Crow's Foot for cardinalities between entities and relationships. Users drag entity rectangles and relationship diamonds from the ER palette to model data schemas. Common applications include conceptual for relational databases. While manual creation is emphasized, yEd's automatic layout features can enhance arrangement for these diagram types once elements are placed.

Automatic Layout

yEd provides a suite of built-in automatic layout algorithms that arrange elements such as nodes and edges with minimal user intervention, enabling the creation of clear and aesthetically pleasing visualizations from imported or manually created graphs. These algorithms compute optimal positions and paths based on graph structure, supporting efficient production for various applications. The force-based, or organic, layout simulates physical forces like attraction and repulsion between nodes to achieve a natural, balanced arrangement that highlights clusters and symmetries while minimizing edge crossings and ensuring uniform edge lengths. It is particularly suited for general graphs, such as social networks or bioinformatics diagrams, where an organic appearance is desired. Key parameters include node sizing options for compact placement, straight-line or polyline edge routing to avoid overlaps, and support for grouping to preserve hierarchical structures during arrangement. For directed acyclic graphs (DAGs), the hierarchical layout organizes nodes into discrete layers, directing most edges from top to bottom or left to right to reduce crossings and emphasize flow. This style is ideal for workflows, entity-relationship models, or UML diagrams. Parameters allow for automatic node sizing based on content, edge routing via orthogonal, polyline, or octilinear styles, and grouping to maintain nested hierarchies. The orthogonal layout routes edges exclusively in horizontal and vertical segments, producing grid-like diagrams with few bends and no overlaps, which enhances for structured visuals. It works well for flowcharts, diagrams, or database schemas. Adjustable parameters encompass node sizing for flexibility, orthogonal edge routing to minimize crossings, and grouping capabilities for . Tree layout algorithms arrange hierarchical data in rooted structures, supporting styles like radial or standard to visualize parent-child relationships without cycles. Commonly applied to organizational charts or representations, it features parameters for customizable node sizing, edge routing options including straight-line or orthogonal paths, and grouping via subtrees for complex hierarchies. These algorithms, derived from the yFiles diagramming library developed by yWorks, can be applied with a single click via yEd's Layout menu to any , including those imported in or built manually. They accommodate key customizations such as node sizing, edge routing preferences, and grouping support across all styles, allowing users to tailor results to specific diagram types like UML without manual repositioning.

Data Import and Export

yEd supports a variety of formats to facilitate the creation of diagrams from external sources, enabling users to convert structured into visual representations such as nodes and edges. Key formats include spreadsheets (.xls), which use a wizard to transform tabular into matrix or diagrams, allowing customization of node labels, properties, and styling during the process. The GEDCOM format (.ged) is specifically supported for importing genealogical to generate diagrams automatically. Additionally, text-based graph formats like GML (.gml) and TGF (.tgf), as well as the YGF (.ygf), can be imported to load existing graph structures. For more flexible data integration, yEd handles generic XML files through XSLT transformations that convert them into the GraphML format, with predefined stylesheets available for specific schemas such as build scripts and ontologies. The native format for yEd is (.graphml), an XML-based standard that preserves all diagram properties, including custom attributes, styles, and layout information, making it ideal for saving and loading editable diagrams. During imports, yEd performs automatic conversions, mapping imported data to graph elements like nodes and edges, while providing options to apply predefined or user-defined styles to enhance visual consistency. On the export side, yEd offers multiple formats to share or publish diagrams, ranging from raster images to and text-based representations. Bitmap exports include , , , and BMP, suitable for standard image sharing, with support for splitting large diagrams into multiple images or HTML tables for better manageability. such as , , EPS, and EMF preserve scalability and quality, with and additionally embedding hyperlinks and tooltips for interactive use. HTML export generates image maps that retain clickable elements from the diagram. For text-based outputs, yEd can export to GML and TGF, which provide simple, human-readable representations of the graph structure without visual styling. These export capabilities ensure diagrams can be integrated into documents, web pages, or further processed in other tools, while the native format maintains full editability upon reloading.
