Sometimes, data takes on a life of its own! After looking through our gallery and seeing the amazing analysis of milk cow production that Kate Golden at Wisconsin Watch produced, he took his own data on milk prices and mashed it with her visualization. Take a look at his analysis here.

As the milk cows in Wisconsin have become more productive, the wholesale price of milk(inflation adjusted) has dropped. One has to wonder if this trend can continue, or if Wisconsin milk cows have reached their full capacity. Either way, Mark Perry and Kate Golden will be here to keep us up to speed.

What we like about this viz

Color legend axes: The nemesis of any dual axis graph is its color legend. Which axis corresponds to which line? By coloring the axes the same as their representative line, the guesswork is reduced.

Thanks for the interesting graph. The only thing about a graph like this is that it does not show how the whole system is linked and the side effects.

We've tripled the amount of milk from a cow but it has also caused the use of hormones, antibioties, mastitis for the cow, and lameness.

Just like humans aren't "units of production" to the contrary view of economists, I would like to think the same applies for other animals like dogs and cows. It's important to keep a viewpoint, from a systems thinking standpoint.

KS, thanks for your comment. There is certainly more to this viz than the bare production figures. If you find some data on it, you should visualize it!
