From the developer:
macSVG can produce dynamic, high-quality graphics, and animation for HTML5 web views that work on most major desktop and mobile platforms. macSVG uses the standard macOS WebKit framework for interactive editing and rendering of SVG documents, in addition to several Cocoa plug-in bundles for editing SVG elements and attributes.
