This example shows a state diagram for data loading with four states—Idle, Loading, Succeeded, and Failed—and the transitions between them. It uses Mermaid.js to parse the `stateDiagram-v2` definition and render the SVG, with custom styling applied via `styleSVGText` and `scaleSVG`. The code waits for the Inconsolata font to load using the Font Loading API before rendering, and overrides Mermaid’s default styling (text fill, font family, and label backgrounds) through CSS and JavaScript to ensure visual consistency.

Data Loading State Diagram

A visual state diagram showing the flow of data loading states using Mermaid.js.

Overview

This project displays a state diagram with the following states:

Idle: Initial state, waiting for data load request
Loading: Active data loading in progress
Succeeded: Data loaded successfully
Failed: Data loading failed

Fork of Styled Mermaid Diagram

This example shows a Mermaid.js state diagram that depicts the lifecycle of a data loading process (Idle, Loading, Succeeded, Failed) for a web application. The visualization is rendered dynamically by fetching the diagram definition from a separate `.mermaid` file and passing it to Mermaid's `render` method. The code uses Mermaid's `initialize` API to configure theme variables and spacing, and it waits for the Inconsolata font to load before rendering. After the render, the HTML is post-processed to enforce custom styling on SVG elements, including specific font sizes and black fills for state and edge labels.

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.

Fork of Styled Mermaid Diagram

This example presents a state diagram built with Mermaid.js, visualizing a complete sales and delivery pipeline with inbound engine, entry paths, intake qualification, and multiple sales paths. It highlights feedback loops that route leads through nurturing touchpoints and qualification gates, ultimately leading to closed-won deals or blocked outcomes. The code fetches the diagram definition from `diagram.mermaid`, renders it via `mermaid.render`, and applies custom styling to ensure consistent font rendering. The visualization uses the Inconsolata font, loaded through the Font Loading API before Mermaid initializes.

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.

Fork of Mermaid Starter

This example presents a Mermaid.js flowchart depicting the VizHub Studio integration workflow, showing how a cloud platform, client agency, and publishing pipeline connect. The diagram defines three subgraphs with custom CSS styling classes for visual distinction. It uses the Mermaid `render` function to convert a diagram definition string into SVG, which is then inserted into the page via `innerHTML`. The page is styled using a separate CSS file.

Mermaid Starter

This visualization displays a simple flowchart using Mermaid, rendering a sequence of processes and decisions from a start node to an end node. The diagram is generated in an HTML page using Mermaid's `initialize` and `render` APIs, with an import map loading the library from a CDN. The diagram definition is stored as a string and rendered into a styled container with a grayscale theme. The example supports easy modification of the diagram syntax through the JavaScript code.

Fork of VizHub Runtime State Machine Diagram

This animated state machine diagram illustrates the runtime lifecycle of code changes in VizHub, showing transitions between IDLE, ENQUEUED, PENDING_CLEAN, and PENDING_DIRTY states with notes explaining each phase. It uses Mermaid.js to render a stateDiagram-v2 from an embedded definition string, with custom theme variables and CSS overrides for gray note backgrounds and consistent typography via the Nunito font. The visualization is generated client-side as inline SVG, with post-render DOM manipulation to ensure styling consistency.

Fork of SaaS Infrastructure

This example visualizes the end-to-end product lifecycle, from ideation through post-launch, using a Mermaid flowchart. The diagram groups phases into colored subgraphs and connects tasks with directional arrows, including a feedback loop back to ideation. It is rendered in the browser via the Mermaid JavaScript library, which fetches the diagram definition from a local `.mermaid` file and converts it to SVG. Styling is applied through CSS and JavaScript, using the Inconsolata font and custom theme variables to ensure monochrome nodes, black borders, and consistent typography.
