Diagrams.net logo vector PNG | Draw.io flowchart icon | Connected nodes diagram symbol | Visual workspace and diagramming brand mark

The Diagrams.net logo, often still associated with its former name draw.io, is a clean and modern visual mark that immediately communicates the idea of diagrams, structure, and connectivity. Set within a vibrant orange square with subtly rounded corners, the logo features three white rounded squares arranged in a triangular pattern. One square is positioned at the top center, while two others sit at the bottom left and bottom right. The three nodes are connected by white lines that form a simple network or flow structure. This minimal, geometric composition captures the essence of a diagram: discrete elements linked together by relationships and flows. The use of a flat design style and a long diagonal shadow from the central motif evokes contemporary app icon aesthetics and signals that Diagrams.net is a digital, tool‑centric product. The bold orange background is a standout feature, serving both aesthetic and functional purposes. Orange is often associated with creativity, energy, and clarity, all of which reflect the mission of Diagrams.net: to help individuals and organizations visually map out ideas, systems, and processes. The color’s high contrast against the white diagram symbol allows the icon to be easily recognizable even at small sizes, which is essential for application launchers, browser tabs, and integration menus. The slight rounding of the square’s corners softens the icon’s appearance, making it approachable, while still maintaining a strong, professional presence suitable for enterprise and technical use. At the heart of the logo is the trio of rounded white squares linked by straight edges. These nodes represent the basic building blocks of diagrams: shapes such as process steps, system components, entities, and conceptual blocks. The connecting lines symbolize relationships, dependencies, data flows, or logical sequences. By abstracting all diagram types—flowcharts, network maps, organizational charts, UML diagrams, mind maps, and more—into this simple three‑node network, the logo becomes a generalized symbol for structured thinking and visual organization. The rounded corners of the squares echo typical diagram shapes found within the application itself, reinforcing brand consistency between the logo and the user interface. The long diagonal drop shadow, cast from the diagram symbol onto the orange background, adds depth and visual interest while remaining within the flat‑design paradigm. It suggests that the central diagram is slightly elevated, as if it were a card or tile floating above a surface. This visual metaphor aligns with the idea of working on diagrams as objects that can be moved, edited, and shared in a collaborative digital workspace. The shadow also subtly points from the upper left to the lower right, hinting at a typical left‑to‑right flow in diagrams and user workflows. Even though the design is minimalist, this shadow introduces a feeling of dimensionality and modern software design language. Diagrams.net, historically known as draw.io, is a widely used web‑based and desktop diagramming platform. It enables users to create a broad range of diagrams, from simple flowcharts and decision trees to complex network topologies, engineering schematics, and enterprise architecture maps. The service is especially known for its tight integration with popular collaboration environments such as Google Drive, OneDrive, GitHub, GitLab, Atlassian Confluence, and Jira. Many organizations adopt Diagrams.net because it offers powerful diagramming capabilities in a browser‑based, open, and cost‑effective model, which stands in contrast to more closed or expensive legacy diagramming tools. The company behind Diagrams.net emphasizes openness, flexible deployment, and data control. Users can run the application in the cloud or on‑premises, store diagrams locally or in their own preferred cloud storage provider, and integrate the tool into existing development and documentation workflows. This philosophy is indirectly reflected in the logo’s visual language. The three connected nodes can be interpreted as separate systems or repositories that are linked through clear pathways. In this sense, the logo reflects interoperability: different parts of a software or organizational ecosystem communicating through structured relationships. The simple geometry and high recognizability of the logo also speak to the product’s core value proposition: making complex information easier to understand. Diagrams.net targets audiences ranging from software engineers and system architects to business analysts, educators, and students. All of these users share a need to turn abstract concepts and complicated processes into visuals that can be shared and discussed. The logo’s clarity mirrors this mission. It does not rely on text, gradients, or intricate pictorial elements; instead, it focuses on a universally understood visual archetype of connected blocks. Furthermore, the icon’s modular feel echoes the modularity of the software itself. Within Diagrams.net, users assemble diagrams from a rich library of shapes: servers, databases, UML elements, BPMN symbols, UI wireframe components, and more. Each diagram is built block by block, connection by connection, just as the logo is built from three simple shapes and three simple lines. The branding thereby underscores the notion that even sophisticated systems can be constructed from basic, understandable components, a principle central to systems thinking and software design. By choosing a purely symbolic mark without accompanying wording in its core icon, the brand also communicates international reach and adaptability. The logo functions equally well across languages and markets, since its meaning—“linked shapes, organized information, structured diagrams”—is largely universal. This is particularly suitable for a tool widely adopted by global development teams and multinational organizations collaborating across borders and time zones. The brand’s visual economy ensures that the logo remains clear on screens of all sizes, from small mobile displays to large monitors used during technical presentations and workshops. In summary, the Diagrams.net logo is a carefully balanced combination of simplicity, symbolism, and modern visual design. The orange square and white network of rounded nodes work together to convey creativity, clarity, and connectivity. The design aligns closely with the product’s purpose: enabling users to construct visual representations of systems, workflows, and ideas. Its minimalism ensures flexibility and recognizability in diverse digital environments, while its geometric structure mirrors the modular, block‑and‑connection nature of diagramming itself. As Diagrams.net continues to serve developers, IT professionals, business users, and educators worldwide, this logo acts as a succinct emblem of visual thinking and collaborative problem‑solving in the digital age.
