Scotch Rankings

Based on Scott Gregoire's Scotch ranking methodogy.

The scatterplot and table feature:

Mike Bostock's work with scatterplots
Robert Grove's implementation of the force-directed layout
Responsive properties that allows the browser to resize the SVG through the ViewBox attribute
Table built using D3 and that has a fixed header with a scrollable y-axis

Both the scatterplot and the table are constructed from data directly on Scott's GitHub repository.

The table above lists the whiskies that rank in the top ten for both sorting orders. Put another way, the table contains the whiskies colored either dark or light green in the scatterplot. The table also contains the ranks of scotches under both sorting orders.
                    </br>For example, "Complexity then Balance Rank" lists the rank of a scotch when the scotches are sorted by "Complexity" first then "Balance." "Complexity" and "Balance" are the "Complexity" and "Balance" scores, respectively. In the table, notice that Bruichladdich, Old Pulteney, and  Scapa are unambiguously the top three scotches.
