SVG-edit
SVG-edit is a web-based free and open-source vector graphics editor. It can be used to create and edit Scalable Vector Graphics images from within a web browser, not requiring additional software installation.
Overview
SVG-edit is a cross-browser web-based, JavaScript-driven web tool, and has also been made into browser addons, such as an addon for Firefox, a Chrome extension, and a standalone widget for Opera. There's also an experimental SVG editing extension on MediaWiki that uses SVG-edit.SVG-edit consists of two major components: svg-editor.js and svgcanvas.js. These components work cooperatively. File svgcanvas.js can be used outside of SVG-edit, allowing developers to create alternative interfaces to the canvas.
