    Line9 is a new rendering engine for Mermaid flowchart diagrams that aims to remove the need for manual adjustment of layout. Mermaid is a popular text-based language for describing multiple types of diagrams. Several Mermaid rendering engines already exist. Most, like the original mermaid.js, use Dagre or ELK graph drawing libraries to automatically lay out their diagrams. I’ve used Mermaid for the past four years but often recreated my flowcharts in a diagram editor so that I could modify the layout to something that better suited my needs. Use Line9 when you want an automatic flowchart…

    mermaidonline.live is an online platform designed to make working with Mermaid diagrams more accessible, efficient, and user-friendly. Mermaid itself is an open-source JavaScript-based tool that allows users to create diagrams and visualizations using plain text syntax. Instead of manually drawing flowcharts, sequence diagrams, or Gantt charts, users can simply write text in Mermaid’s simple Markdown-like syntax, and the tool automatically generates the visual output. While Mermaid is widely used by developers, technical writers, and project managers, it often requires either local setup or…

    A new feature from Mermaid Chart allows users to easily share text-based diagrams with others. What is Mermaid Chart? It’s an extension of open source diagramming tool Mermaid: https://mermaid.js.org. I created Mermaid to make diagramming more fun again. Mermaid Chart helps to bring this to life. With Mermaid Chart, users can easily generate a wide range of charts – flowcharts and pie charts to sequencing diagrams, user journeys, and Gantt – from simple, markdown-style code. Our new Teams feature means these users can securely share diagrams with others, opening up a clear path for…

    Hey HN, I built this tool because my personal diagramming workflow was broken, and I wanted to automate it. When creating diagrams, I have two conflicting needs. For logic and structure, I prefer Mermaid.js here. It’s deterministic, version-controllable, and lets me tweak the logic easily until it matches exactly what’s in my head. For aesthetics, I need the final result to look like a high-end infographic for presentations, which Mermaid (and standard tools) are bad at. Before Nanobanana Pro came out, AI image generation cannot generate good visual presentation for diagrams because it…

    Hello HN, It has been a while since I contributed to the web, so I decided to get back in shape and publish "something". This app is a POC of "what if diagrams were more dynamic". I'm a software engineer by trade, and with conventional tools, I often times struggle to explain flows of data in complex software systems. I got inspired by video games like The Incredible Machine and Factorio, as in some ways, software systems tend to become Rube Goldberg-esque machines ;) As a side quest, I also wanted to craft diagrams faster than text-based tools (ex: mermaid), as I am always forgetting their…

    Hey HN, I made this because I wanted a fast editing experience when making flowcharts. Other tools (bottom)require clicking and dragging (or editing code). Knotend is keyboard centric and is supposed to feel more like editing a doc than dragging around boxes and arrows. I've tested in on safari and chrome desktop. Its difficult to use on mobile but you can view existing charts. I'd appreciate your feedback on how you use it, the design, any bugs etc. Thank you.
