Now, using that same data file, perhaps we can get a general idea of what D3 may be able to do for us in the form of valuable data visualization.

We'll get into the details in the next section, but for now, all we need to do to get started is to create an HTML page based upon a bubble chart template downloaded from the D3 website (this particular template utilizes the D3 flare class libraries to create a bubble chart from our data file).
