Basic Mermaid Diagram Example

Styled Mermaid Diagram

This example shows a state diagram for a data loading process, depicting transitions from Idle to Loading, and from Loading to either Succeeded or Failed states. The visualization uses Mermaid.js to render the diagram, with JavaScript code that fetches the diagram definition from a separate file and renders it as SVG. The styling is customized with the Inconsolata monospace font, and the JavaScript API waits for document fonts to load before initializing Mermaid's rendering engine.

SaaS Infrastructure

This example shows a full-stack web application architecture through a flowchart diagram rendered with Mermaid.js. The diagram organizes services into four labeled layers—Client, Application, Infrastructure, and External Providers—and connects them with directional arrows indicating relationships such as HTTP requests, database queries, and token verification. The code fetches the diagram definition from a separate `diagram.mermaid` file and renders it dynamically using Mermaid's JavaScript API, applying custom styling through Inconsolata font and theme variables. The implementation relies on `fetch` to load the source and `mermaid.render` to generate the SVG output.

VizHub Runtime Web Worker and Iframe Concept

This example visualizes the build process of a VizHub runtime by showing a flowchart where code changes feed into the runtime, which sends build inputs to a web worker, receives the build result, and then sets the `srcdoc` for an iframe. The diagram is rendered using the Mermaid.js library, which is configured with custom styling through CSS variables and the `mermaid.initialize` API with theme variables for fonts and colors. The Mermaid diagram definition is written in flowchart syntax and rendered as SVG via the `mermaid.render` method.

VizHub Runtime State Machine Diagram

This example visualizes the state machine of the VizHub Runtime Environment as an interactive Mermaid diagram, illustrating four states—IDLE, ENQUEUED, PENDING_CLEAN, and PENDING_DIRTY—and their transitions triggered by code-change events and build completion. Built with the Mermaid library (mermaid.render), it uses a stateDiagram-v2 definition embedded directly in an HTML page, with custom CSS and themeVariables for styling nodes, edges, and gray note boxes. The diagram animates through state transitions on load, conveying the runtime’s logic for handling concurrent code changes during builds.

This example is an interactive flowchart editor that renders diagrams from text-based descriptions. Users input flowchart syntax into a text area, and the flowchart.js library parses and draws the result onto an SVG canvas. The code demonstrates custom styling options, including colored start and end nodes, conditional branches, and parallel tasks. It integrates D3.js for DOM manipulation to build the interface elements, while Raphael and jQuery handle the flowchart rendering and click interactions on subroutines.

Data Loading State Diagram

This example visualizes the sequence of interactions between a user, a web page, and a server during data loading using a sequence diagram. It shows the initial page load, subsequent data requests, and how the page updates with the retrieved information. The diagram is rendered with the Mermaid.js library, which parses a markdown-like diagram definition fetched from a separate file. Custom CSS and JavaScript ensure the diagram uses the Inconsolata font and applies styling to actors, labels, and edges for clarity.

Untitled

This example shows an interactive flowchart generator where users input flowchart syntax into a textarea and press a button to render the diagram. The visualization uses the flowchart.js library to parse the text and draw the chart onto an SVG canvas, while D3.js (v5) handles DOM manipulation to create the input interface and dashboard layout. The code defines flow states like "past", "current", and "future" with custom colors and styles, and includes click handlers for subroutines that trigger alerts. It integrates Raphael for SVG rendering, jQuery for event handling, and custom CSS for end-element styling.
