Try the DEMO.
Playing around with a simple SVG editor web app that has zero runtime dependencies.
Working towards building a very basic editor, this demo doesn't do much yet, but you can try it out. It has a couple shape tools, basic selection/move, delete, undo/redo.
This demo uses modern web standards and technologies that are not broadly supported on the web, such as the Native File System API and Custom Elements. Some features (such as loading/saving to the native file system) will be degraded in browsers that do not support the related web specification.
