Many enthusiastic users and groups, see Useful references below. SVG is supported in Adobe tools, Visio (Microsoft), Corel Draw 11, and as an export format by ESRI ArcGIS. There are several open source applications and software libraries that can read and write SVG images. SVG is a preferred format for the FCLA Digital Archive. Browser support has varied with many complaints about lack of support by Internet Explorer. An infographic from late 2014 indicates that support is full in Safari, Firefox, Chrome, and Opera, support in IE started with IE 9 and support in Android with version 4. A more detailed presentation of SVG feature support is available from caniuse.com. A feature support comparison is also available at Comparison of layout engines (Scalable Vector Graphics) on Wikipedia. However the Wikipedia table may not have been kept up to date. Testing SVG support across browser engines explores support by the engines used in various browsers on a test SVG file. What these tables and tests suggest is that some features are less widely supported than others. Support for ICC profiles and some font-related capabilities may be examples of less widely supported features. In some contexts, animations and audio are not rendered. The October 2011 EPUB_3 specification for Electronic Publications uses a restricted subset of SVG_1_1 as a content document format for graphics, including use as a top-level format for comics and graphic novels. Not supported in EPUB_3 are animations and embedding of ‘foreign objects’ in forms other than XHTML. SVG files can be used for animations but in 2013 there appeared to be little or no practice of doing this. Most web sites present simple animations as GIF_89a files and more complex animations and interactives as Flash SWF_7 or SWF_8 files (or later versions). Commentators with an interest in animation, including advocates for SVG as a publicly disclosed format, have compared SVG and SWF but they note that the powerful authoring software available for Flash gives SWF the edge. SVG was originally developed through a process that began in 1996, with a call for responses to W3C Scalable Graphics Requirements. According to Secret Origin of SVG, there were six proposals submitted by 1998, and SVG was particularly influenced by VML (Vector Markup Language), already deployed in Microsoft products, and PGML, a proposal from a partnership led by Adobe and using the same imaging model as in Postscript and PDF.
