What's New in Diagrammix 3
Diagrammix 3.8
This release focuses on building richer infographics faster — with live layouts, new ways to construct shapes, reusable components, and artboards for exporting finished pieces.
Live Force-Directed and Organic Layouts
Two physics-based algorithms join auto-layout, with live animation: turn on Live, drag a node, and the rest of the diagram re-flows around it. Turn Live off to keep the result.
Combine Shapes with Boolean Operations
Build custom outlines from simple parts with Edit → Combine: Union, Subtract, Intersect, and Exclude.
Reusable Elements with Text Slots
Save any composition as a reusable element, then drag copies from the palette. Every text becomes a fill-in slot with a placeholder.
Artboards
Mark fixed-size frames for slides, social posts, or A4 pages, give each its own background, and export them individually or all at once as PNG or SVG at 1×–3×.
Step and Repeat
Edit → Repeat… (Shift+Cmd+D) makes evenly spaced copies in a line or around a circle.
Smoother Connectors and Multiple Labels
Connectors can be Smooth (curved) or have rounded corners, and each connector can carry several labels — at the start, middle, end, or along the path.
Vector Path and Polygon Editing
Edit the nodes of any path or polygon: insert and delete nodes and switch between corner, smooth, and symmetric points.
Inner Shadows, Canvas Gradients, and Artwork Tinting
- Inner shadows for a pressed or embossed look → Shadows & Effects
- Gradient and texture canvas backgrounds → Canvas Background
- Tint SVG artwork in any colour → Working with Images
Mermaid Gantt and Pie Charts
Insert Mermaid gantt and pie diagrams — rendered as a timeline with sections and task bars, and as a pie chart with a legend.
Page Layout Preview
Turn on View → Show Page Layout to see where print pages fall directly on the canvas.
Layers Panel with Items
The Layers section of the Inspector now lists every item in each layer, with per-item visibility and locking, renaming, and drag-to-reorder.
Rename Document Tabs
Double-click a tab (or right-click → Rename) to give each page of a document a meaningful name.
More for AI Assistants
Connected AI assistants gained new MCP tools — including a radial diagram generator (segmented rings, circles, and petals) and per-artboard Visio export.
And More
Significant performance improvements, plus many bug fixes and refinements throughout the app.
Diagrammix 3.7
Mind Maps
A dedicated mind-mapping mode for capturing and organizing ideas radially.
- Start a map with the Mindmap tool, then grow it with the keyboard:
Tabfor a child,Returnfor a sibling,Shift+Tabfor a parent - Choose from eight structures — Mind Map, Logical, Org Chart, Tree, Catalog, Fishbone, Timeline, and Vertical Timeline
- Built-in themes (Default, Vibrant, Muted, Dark), per-node icons, shapes, group frames, and summaries
- Import from and export to Markdown, OPML, and XMind
Sticky Notes with Images
Drop quick, resizable notes onto the canvas — now with attached images.
- Create notes with the Sticky Note tool
- Attach one or more images to a note from its action toolbar and manage them in an image gallery
- Perfect for moodboards, annotations, references, and brainstorming
Custom Styles
Save your own reusable diagram styles alongside the built-in canvas themes.
- Duplicate a built-in style (Sketch, Comic, Blueprint) or start from scratch, then fine-tune every parameter
- Custom styles appear in the Autostyle menu and apply to your whole document in one click
- Recreate a look from a reference image automatically over MCP
Custom Templates
Build your own notation packs of shapes and arrowheads.
- Author custom SVG shapes and custom connector arrowheads
- Manage packs from View → Manage Custom Templates…; your packs appear under Custom in the template picker
- Import, export, and share packs with your team
A Redesigned Mermaid Workflow
Mermaid import is now a preview-first, round-trippable experience.
- Preview and validate Mermaid before it lands on the canvas — see node and connector counts, with errors flagged inline
- Keep editing in Mermaid — every imported diagram keeps its source, so you can reopen the
</>editor and re-render at any time
Control Diagrammix from AI Assistants (MCP)
Diagrammix ships with a built-in MCP server so AI assistants like Claude and Codex can read and build your diagrams.
- Describe what you need in plain language — the AI places symbols, connectors, and layouts for you
- Replicate styles and shapes from an image — hand the AI a reference picture and it produces a matching custom template and style
- Works with Claude Desktop, Claude Code, Codex, and any MCP-compatible client
Icon Sets in the Clipart Manager
The Clipart manager now includes a browsable library of icon sets, organized by category, alongside your own saved clipart.
More Layout Options
Auto-layout gained new algorithms beyond the classic hierarchical layout — including layered, tree, radial, circular, force-directed, organic, and grid arrangements.
Move Sticky Spots with a Dedicated Tool
A new Move Sticky Spot tool lets you reposition attachment ports precisely, snapping connector endpoints to a shape's exact contour.
Improved Copy Style Tool
The Copy Style (format painter) tool is smarter: it copies styling across element types, intelligently maps properties between shapes, connectors, vector paths, and images, and re-stamps custom style variants so complex looks carry over faithfully.
