Create UML Class Diagrams in Confluence — Free with Mermaid

· 16 min read

Class diagrams are the standard way to model object-oriented systems. They show the classes in your codebase, their attributes and methods, and the relationships between them -- inheritance hierarchies, composition, aggregation, and simple associations. Whether you are documenting a domain model, onboarding new engineers onto a codebase, or collaborating on a design before writing a single line of code, a UML class diagram communicates structure faster than paragraphs of prose.

If your team uses Confluence for technical documentation, embedding class diagrams directly on your pages keeps your design docs next to your architecture decisions, runbooks, and sprint planning notes. With Mermaid Plus for Confluence, you can write class diagrams in plain text and render them instantly, no external drawing tool required.

ER Diagrams in Confluence: How to Add, Create, and Render Database Schemas

· 21 min read

An ER diagram (entity-relationship diagram) visualizes a database schema — the tables, columns, primary and foreign keys, and the relationships between them. If your team documents data models, API contracts, or system architecture in Confluence, embedding ER diagrams directly on the page keeps the schema next to the prose instead of stranded in an external tool as a stale screenshot.

Confluence has no built-in ER diagram support, so you add it with a Marketplace app. The approach below uses Mermaid Plus for Confluence, which renders ER diagrams from plain text — meaning diagrams version, diff, and search alongside the rest of your documentation.

What you'll learn
  1. How to add an ER diagram to any Confluence page
  2. The full Mermaid erDiagram syntax — entities, attributes, key types, cardinality
  3. Three copy-paste examples (library, e-commerce, SaaS multi-tenant)
  4. Common mistakes and how to fix them

Entity-Relationship (ER) diagrams are the standard way to visualize database schemas. They show the tables in your database, the columns in each table, primary and foreign key constraints, and the relationships between tables -- one-to-one, one-to-many, and many-to-many. Whether you are designing a new database from scratch, documenting an existing schema for onboarding, or collaborating on a data model before writing migration scripts, an ER diagram communicates structure faster than any amount of prose.

How to Create Gantt Charts in Confluence — Mermaid Examples

· 15 min read

Gantt charts are one of the most widely used visual tools in project management. They give teams a clear, time-based view of who is doing what, when tasks start and end, and how dependencies chain together across a project lifecycle. Whether you are planning a software release, coordinating a marketing campaign, or managing a sprint backlog, a Gantt chart turns a flat task list into a timeline your whole team can read at a glance.

Confluence is where many teams already store their project documentation, meeting notes, and decision records. Embedding Gantt charts directly on Confluence pages keeps your project visuals alongside the context your team needs, instead of burying timelines in a separate project management tool that nobody checks. With Mermaid Plus for Confluence, you can write Gantt charts using plain text syntax and see them rendered instantly on the page.

Create Mermaid Diagrams on Jira Issues — Flowcharts, Sequence & More

· 18 min read

Jira issues are where your team tracks bugs, features, and tasks every day. But describing complex processes, API interactions, or system designs in plain text often leads to confusion and misalignment. Mermaid Plus Diagrams for Jira solves this by letting you create and embed Mermaid diagrams directly on any Jira issue, so the visual context lives exactly where the work happens. No external tools, no attached images that go stale, no switching between tabs.

Create Mind Maps in Confluence — Free with Mermaid Plus

· 12 min read

Mind maps are one of the most effective ways to capture ideas, organize thoughts, and brainstorm with a team. Unlike linear notes or bullet lists, mind maps radiate outward from a central topic, making it easy to see relationships between concepts at a glance. If your team already uses Confluence for documentation, meeting notes, and project planning, adding mind maps directly to your Confluence pages keeps brainstorming sessions alongside the rest of your team's knowledge.

In this tutorial, you will learn how to create mind maps in Confluence using Mermaid syntax and the Mermaid Plus for Confluence app. Every example is copy-paste ready, so you can drop it straight into a Confluence page and start organizing your ideas immediately.

Create Pie Charts in Confluence — Free with Mermaid Syntax

· 18 min read

Pie charts are one of the simplest and most effective ways to communicate proportional data. Whether you are reporting survey results, breaking down a project budget, or showing how your team allocates time across activities, a pie chart turns a list of numbers into a visual that anyone can read in seconds. Confluence is where your team already stores reports, retrospectives, and planning documents, so embedding pie charts directly on those pages keeps your data alongside the context that explains it.

With Mermaid Plus for Confluence, you can create pie charts and other data visualizations using plain text syntax. No image exports, no spreadsheet screenshots, no broken attachments. You write the code once, and the chart renders directly on the Confluence page, updating whenever you edit the underlying data.

How to Create Sequence Diagrams in Confluence (Mermaid Examples)

· 13 min read

Sequence diagrams are one of the most practical tools in a software team's documentation toolkit. They show how objects, services, or actors interact over time, making them ideal for documenting API flows, authentication processes, microservice choreography, and error-handling logic. If your team uses Confluence for documentation, embedding sequence diagrams directly on your pages keeps architecture docs alongside everything else your team needs.

In this tutorial, you will learn how to create sequence diagrams in Confluence using Mermaid syntax. Every example is copy-paste ready, so you can drop it straight into a Confluence page and see the result immediately.

Create State Diagrams in Confluence — Mermaid Syntax & Examples

· 17 min read

State diagrams (also called state machine diagrams) model how a system transitions between discrete states in response to events. They are essential for documenting order lifecycles, user authentication flows, CI/CD pipelines, IoT device behavior, and any system where the current state determines what happens next. If your team uses Confluence for technical documentation, embedding state diagrams directly on your pages keeps your design decisions alongside runbooks, architecture decision records, and sprint planning notes.

In this tutorial, you will learn how to create state diagrams in Confluence using the Mermaid stateDiagram-v2 syntax. Every example is copy-paste ready, so you can drop it straight into a Confluence page and see the rendered result immediately.

Best Diagram Tool for Confluence — Mermaid vs Excalidraw vs Graphviz

· 8 min read

Looking for the best diagram tool for Confluence? Confluence has no built-in diagramming, so every team adds a Marketplace app — but the right choice depends entirely on what you draw and how you prefer to work. This guide compares the three strongest options — Mermaid Plus for Confluence, Excalidraw plus Whiteboards for Confluence, and Graphviz Charts for Confluence — so you can pick the diagram tool that fits your team instead of guessing.

Quick answer

For most Confluence teams, Mermaid Plus is the best diagram tool — it covers the widest range (29 diagram types), is the easiest to learn, and renders text into diagrams that version cleanly with your docs. Pick Excalidraw Plus if you need freehand whiteboarding and wireframes. Pick Graphviz Charts for dense network and dependency graphs. Many teams install more than one.

What you'll learn
  1. Which diagram tool fits each type of Confluence team
  2. The strengths and trade-offs of Mermaid, Excalidraw, and Graphviz
  3. Pricing, hosting, and integration differences
  4. A decision framework so you can choose in under a minute
