#TweakThursday 7: Reciprocal Exploring

The Viz of the Day on 7/13/2016 is the first one from an author in China that I have ever seen. Although some of the description is in Chinese, the viz is understandable by anyone who knows English.

The sensual curves of the sigmoid function and the wild cocktail colors make the viz irresistible to an ordinary man like me. The viz obviously seduced the committee of Tableau's Viz of the Day as much.

Not familiar with this kind of chart type, I played with it a bit. And I found a few things to tweak.

The viz showed successfully the ingredients in each of the well-known cocktails. But I also wanted to know the reverse: for an ingredient, how many cocktails contain it? All the data are available to answer this reciprocal question. I also needed to visualize the percentages of ingredients in a cocktail.

So, initially this viz is about Cocktails > Ingredients discovery. My tweaks make it a viz of Cocktails <> Ingredients reciprocal relationship, based on the same data set.

Here are my major tweaks:

1.Ordering data 
Putting order in the view is always a good practice for viewers to easily consume information. So I made all the following ordering from left to right.
- Order cocktails by the number of ingredients each contains. That is, from the most sophisticated cocktail (Long Island Iced Tea), to the least one.
- Order ingredients by the number of cocktails each is included in. That is, from the most used ingredient (Vodka) to the least one.

2.Adding visualization 
That shows how many cocktails one ingredient is contributing to. Four more action filters and two tooltip sheets are added.

3.Use visual tooltips to list details
The sigmoid chart is not the best chart type for the view. A horizontal bar chart can do a better job. Two tooltips are added: one for the cocktails and the other for the ingredients.
