Circles requires JavaScript and HTML5 canvas to work. Circles is supported on the following browsers:
Circles also works on other modern browsers, such as Opera, though support for these browsers is not a priority.
With the release of the HTML5 version of Circles, the Flash-based line has entered the bugfix-only mode. This means that further releases of Circles Flash will contain only bug fixes, new features will be introduced only in HTML5-based version. HTML5 version is more compact and does not depend on third party plugins. In some corporate environments you may still need to use the flash version though (because only old browsers are available, for example).
Unless you need to support older browsers, mainly Internet Explorer 8 or earlier, we recommend migrating to HTML5 Circles.
Easy to integrate, many tuning options, very fast and lightweight.
