Together with the Tag Cloud, actually right above it, a search bar is provided: you can click on any Tag in the Cloud and add it to the search bar, then you can edit the search bar text, and finally search it on some of the most common websites you might want to search on (Google, Twitter, Facebook, Quora, Wikipedia).
In addition, this extension adds an entry to your right-click context menu inside Chrome; the new entry is shown only when you have selected some text inside a page, and allows you to search the selected text with one of the search engines above, or to translate it using Google Translate (by default, it sets translation from an automatically determined language to English). All of these options requires literally two mouse clicks, and they all open the new search page in a new tab/window.
You can install it from the [chrome webstore](http://goo.gl/pQHts), read about it [here](http://mlarocca.github.com/01-14-2013/tagcloud.html), or check the source code [here](http://goo.gl/Lrqiq)
All the charts objects support multidimensional data, have plenty of built-in methods to change style-related details, such as colors, as well as modifying preferences about labels. legend, title, and deciding whether each subcomponent of a multidimensional dataset should be scaled according to global or local maximum.
For 3 out of 4 charts requires that the maximum amount of values that can be represented at the same time is fixed on construction; it is therefore possible to set how much of the oldest data should be discarded when the chart is full, in order to draw new data (or, by default, the chart will discard all of the new data passed)
Finally, the function used to validate data can be set at run time, allowing to make the chart able to accept JSON data or any other format.
