Overview
The React Diagram is a feature-rich architecture diagram library for visualizing, creating, and editing interactive diagrams. It supports creating flowcharts, organizational charts, mind maps, and BPMN charts either through code or a visual interface.
Why choose the Syncfusion React Diagram?
Automatic layout
Automatically arrange nodes based on a predefined layout algorithm.
Seamless data binding
Populate diagrams with nodes and connectors created and positioned based on data from data sources. Without having to write any code, easily convert, map, and consume data in any format in the Diagram by setting a few properties.
Interactive editing
The React Diagram lets users pan and zoom, snap, undo and redo, stencil, resize, and rotate interactively.
Adapts to any resolution
Diagram has a highly responsive layout and an optimized design for desktops, tablets, and phones. It works well on all mobile phones that use iOS, Android, or Windows OS.

React Diagram code example
Get started with the React Diagram using a few simple lines of TSX code, as demonstrated below. Also, explore this React Diagram example, which shows you how to render and configure the component.
import * as React from "react";
import "./App.css";
// import the DiagramComponent
import { DiagramComponent } from "@syncfusion/ej2-react-diagrams";
export default class App extends React.Component<{}, {}> {
render() {
return <DiagramComponent id="diagram" />;
}
}
Real-time collaboration
Multiple users can edit the same diagram simultaneously and see live updates, improving teamwork and efficiency.
- User presence highlight: Each element shows who is currently interacting with it.
- Conflict handling: When multiple users edit the same element, the first user’s changes are applied, and the others are notified of the conflict.
Flowcharts
The React Diagram provides all the standard flowchart shapes as ready-made objects to build flowcharts, making it is easy to add them to a diagram surface in a single call.
Organizational charts
Arrange parent and child node positions automatically with a built-in layout algorithm specifically made for organizational charts.
Mind maps
An layout algorithm is also built for mind map diagrams. Users can define which node should be at the center and which nodes should be placed around it on the diagram surface.
Seamless Visio integration
Import Microsoft Visio (.vsdx) files into the React Diagram and export diagrams back to Visio format, with support for flow shapes, basic shapes, groups, connectors, ports, and annotations.
UML sequence diagram
Visualizes time‑ordered interactions between system participants by modeling lifelines and message exchanges, enabling precise analysis of execution flow, request‑response behavior, and component collaboration.
Nodes
Visualize any graphical object using nodes, which can be arranged and manipulated at the same time on a diagram page. They allow users to:
- Use of many predefined standard shapes.
- Create and add custom shapes easily.
- Fully customize the appearance of a node.
- Design a node UI template and reuse it across multiple nodes.
Connectors
A connector represents a relationship between two nodes.
Types
The React Diagram provides straight, orthogonal, polyline, and curved connector types. Users can choose any of these based on the type of diagram or relationship between the connected nodes.
Bridging (line jumps)
Use bridging (line jumps) to illustrate a connector’s route, making it easy to read where connectors overlap each other in a dense diagram.
Arrowheads
Use different types of predefined arrowheads to illustrate flow direction in flowchart diagrams. You can also build your own custom arrowheads.
Appearance
Like with nodes, the connectors’ look and feel can also be customized in any way. The React Diagram component provides a rich set of properties to customize connector color, thickness, dash and dot appearance, corners, and even decorators.
Line routing
Orthogonal connectors navigate the shortest and most efficient path to prevent overlapping with neighboring nodes.
Avoid connector overlap
The component automatically adjusts connector paths to prevent visual overlap, ensuring clear, distinct routing in complex diagrams. This enhances readability, reduces clutter, and maintains clean connector separation.
Ports (connection points)
Attach connectors to specific places on a node through different types of ports or connecting points.
Labels
Additional information can be shown by adding text or labels on nodes and connectors.
Edit
Users can add and edit text at runtime and mark it read-only if it should not be edited.
Multiple labels
Add any number of labels and align them individually.
Alignment
Labels include sophisticated alignment options: Place inside or outside a node, or at the source or target end of a connector. Automatically align when a node or connector moves.
BPMN editor
The React Diagram includes all standard BPMN (Business Process Model and Notation) shapes, which are essential graphical elements used to visualize business processes effectively within a BPMN diagram.
Swimlanes
The React Diagram supports swimlanes, which are visual elements that represent various components, activities, and responsibilities within a business process.
Containers
Containers organize related elements into clearly defined sections, supporting drag‑and‑drop interaction, flexible layouts, independent styling, and grouped event handling to improve UI clarity, consistency, and overall user experience.
Interactive features
Use interactive features to improve the editing experience of a React Diagram at runtime. Furthermore, easily edit a diagram using a mouse, touchscreen, or keyboard.
Select and drag
Select one or more nodes, connectors, or annotations and edit them using thumbs or handlers.
Resize
Users can resize a node in eight directions and lock a node’s aspect ratio to keep its shape. They can also resize multiple objects simultaneously.
Undo and redo
Undo and redo in the diagramming tools allow users to reverse or reapply actions such as moving, resizing, and creating elements.
Clipboard
Cut, copy, paste, or duplicate selected objects within and across diagrams.
Z-order
When multiple objects overlap, the z-order controls which object is at the top and which is at the bottom.
Snap
Precisely align nodes, connectors, and annotations while dragging just by snapping to the nearest gridlines or objects.
Grouping
Combine multiple nodes into a group and then interact with them as a single object. Nested groups are also possible with our React Diagram component.
Quick commands
Frequently used commands like delete, connect, and duplicate can be shown as buttons near a selector. This makes it easy for users to perform those operations quickly instead of searching for the correct buttons in a toolbar.
Alignment
Our React Diagram Library has predefined alignment commands that enable users to align the selected objects’ nodes and connectors with respect to the selection boundary.
Spacing commands
Spacing commands let users place selected objects on the Diagram at equal intervals.
Sizing commands
Use sizing commands to size selected nodes evenly relative to the first selected object.
Align commands
All the nodes or connectors in the selection list can be aligned to the left, right, or center horizontally, or aligned at the top, bottom, or middle vertically with respect to the selection boundary.
Automatic layout
Automatically arrange nodes using a predefined layout algorithm. The componenet features built-in hierarchical and radial trees, as well as symmetric layouts.
Rulers
Rulers allow users to measure the distance from the origin of the page to nodes or connectors. This is especially useful in creating scale models.
Symbol palette
The React Diagram library includes a gallery of stencils, reusable symbols, and nodes that can be dragged onto the surface of a diagram.
Overview panel
The overview panel helps users navigate large diagrams more effectively. It displays a small preview of the full diagram page that allows users to zoom and pan within it.
Drawing tools
Draw all built-in nodes and connect them with connectors by simply clicking and dragging in the drawing area.
Zoom and pan tools
View a large diagram closely or assume a wider view by zooming in and out. Navigate from one region of a diagram to another by panning across the diagram.
Exporting
Export a diagram to PNG, JPEG, BMP, and SVG image files.
Printing
Print diagrams from the browser. Users can also customize the page size, orientation, and page margin, and fit a diagram to a single page.
Serialization
Save the diagram state in JSON format and load it back later for further editing using the serializer.
Virtualization
Quickly load large diagrams using UI-virtualization techniques, which selectively load the objects that lie within the viewport area. Smooth scrolling performance is achieved using a built-in spatial search algorithm that builds an index based on the element position.
Miscellaneous
In addition to all the features listed thus far, there are many more that enhance the diagramming experience.
Page layout
Give the drawing surface a page-like appearance using page size, orientation, and margins.
Tooltips
Use tooltips to provide additional information about a node.
Additional features
Keyboard navigation
The React Diagram control ensures that every cell is accessible using the keyboard. Major features like sort, select, and edit can be performed using keyboard commands alone; no mouse interaction is required. This helps create highly accessible applications with this control.
Developer-friendly APIs
Developers have full control over the UI and behavior of the Diagram through its built-in, developer-friendly APIs. It allows the customization of even complex Diagram functionalities.
