Team Chart plugin blocked my visual editor

I’ve been using Team Chart plugin with my WordPress site ( https://www.bangladeshscienceoutreach.org ). It worked well but after upgrading to WordPress 3.9.1 I was unable to use the Visual Editor in my site’s control panel. Disabling the plugin Team Chart helped me to get my Visual Editor get into working mode again. I really need to use that plugin in my site but my Visual Editor gets unresponsive when I enable that that plugin. What am I supposed to do now?

Thanks in advance
