Can I get an evaluation license for Circles?

You can try Circles using the on-line demo, you can also download the demo for further experiments. The only limitation of the demo is disabled branding options.

How many nesting levels does Circles support?

The nesting levels are not physically limited but they all must fit on screen at the same time. Your code could implement zooming in and out for deeper hierarchies by reacting to onGroupClick events and replacing the current Circles model with a fragment of the entire model.

What are the requirements of Circles?

Circles requires JavaScript and HTML5 canvas to work. Circles is supported on the following browsers:

  • Chrome: two latest versions
  • Firefox: two latest versions
  • Internet Explorer: version 9 and later
  • Mac OS Safari: version 5 and later
  • iOS Safari: version 4.2 and later

Circles also works on other modern browsers, such as Opera, though support for these browsers is not a priority.

What is the status of Flash-based Circles?

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.

Does Circles require Lingo3G to run?

No, Circles can be used independently of Lingo3G.

Easy to integrate, many tuning options, very fast and lightweight.

Our evaluation found overwhelming support for using Lingo3G.

I’ve shown two board members of our client company what our FoamTree-powered app does. Amazing what a good visualization can accomplish :-)
