Although not necessary for everybody, Visual Composer Extensions allows you to easily show some recent Google Trends on your website. Due to limitations of the Google API, you can only compare 5 trends at a time, but maybe you will find some use of it.
When using “Google Trends” with a Chrome browser, you need to be logged into a Google account in order to view the trend charts. Otherwise Google will return an error in its return feed due to a wrong MIME type detection through Chrome. Other browsers do not seem to have the same problem. This is not an issue with the plugin, but a security restriction from Chrome.
