I'm not the only developer but I made (and still make) GoJS, an interactive diagramming library for the web. https://gojs.net https://gojs.net Most of its popularity is with large companies building their own internal tools where they need diagramming visualization capabilities (layouts, save/load, undo/redo, data binding, etc). So you won't see it too often in the wild, but under the surface it's used in every industry. I love it, and I love HTML Canvas, which I wish was more popular.
