Thanks for your feedback. It seems like there is a problem with the loading of the VML script file (when the Document mode of IE is set to "Default" instead of "Internet Explorer 8"), which is required in older browsers that do not support SVG. I can suggest you to try one of the following approaches:
- Load HtmlChart's scripts explicitly - you can have a look at this help article for more information
- Load only the missing vml.js file immediately after the ScriptManager definition:
You can get this file from our source code package.
Meanwhile, I have logged this issue with a high priority and it will be fixed in the next Latest Internal Build as well as in Q2 2014 SP1. I have also updated your Telerik points for this bug report.
