draw.io
JavaScript client-side editor for general diagramming & whiteboarding
draw.io is a JavaScript, client-side editor for general diagramming and whiteboarding. draw.io, this project, is a configurable diagramming/whiteboarding visualization application. draw.io is jointly owned and developed by JGraph Ltd and draw.io AG. draw.io is a diagramming or whiteboarding application, depending on which theme is selected. It is not an SVG editing app, the SVG export is designed only for embedding in web pages, not for further editing in other tools. The application is designed to be used largely as-is. It's possible to alter the major parts of the interface, but if you're looking for an editor with very specific editing features, the project is likely not a good base to use. That is to say, if you wanted to create/deploy a whiteboard or diagramming application where the functionality in the main canvas is as this project provides, it is more likely to be a good base to use. -

Delaunator
Fast JavaScript library for Delaunay triangulation of 2D points
Delaunator is a fast library for Delaunay triangulation. It takes as input a set of points. The triangulation is represented as compact arrays of integers. It’s less convenient than other representations but is the reason the library is fast. After constructing a delaunay = Delaunator.from(points) object, it will have a triangles array and a halfedges array, both indexed by half-edge id. What’s a half-edge? A triangle edge may be shared with another triangle. Instead of thinking about each edge A↔︎B, we will use two half-edges A→B and B→A. Having two half-edges is the key to everything this library provides. It will also be useful to have some helper functions to go from one half-edge to the next and previous half-edges in the same triangle. We can draw all the triangle edges without constructing the triangles themselves. -

Mermaid.js to SVG Converter
Visualize the diagrams of your projects
While coding with AI assist, I noticed bigger projects need something more rigid as context so the AI coder doesn't stray away when I try to add new features. You know, to keeps its memory fresh and not change the stuff that already works. The trick is to ask the AI to write a diagram in Mermaid.js format that solidifies the structure of the project and then use that as context to keep the AI reminded at all times what the project is as a whole. This will prevent it from changing things its not supposed to change. This standalone offline web app will convert that mermaid.js code into a visual SVG image so that YOU as a human will be able to understand what the AI think about the structure of your projects so you can see it and fix any misconceptions until the diagram is correct for your project. (Source code is included in the html itself. Open it in a web browser to use.) -
