"The `D3Javascript` object takes care of loading the d3 library from the web and then runs the javascript code that is passed to the object. This javascript code is passed to `eval` by the notebook. The local scope has a variable named `element` that is the jQuery object for the `div` tag of the output area. You can use both javascript and d3 commands in this code."
