==Explanation==
This comic graphs the "suggestiveness" of different visualization types, and the winner is {{w|Violin plot|Violin plots}}, hence the title of the comic. A violin plot is a method of plotting data similar to a {{w|box plot}}, but shows the full probability distribution of the data rather than a "box" showing the central two quartiles. This plot can look like the external opening of a human vulva, as do some of those in the violin plot represented in the comic (strictly speaking, this chart is not purely a violin plot; it is a box plot overlaid onto a violin plot).

The chart compares other visualization types' suggestiveness (as female genitalia) to the violin plots and ranks them after how suggestive they are. In the low end we find {{w|pie chart}}, a circular graph divided into "slices" to show proportions, and {{w|Line chart|line graph}} or line chart, a graph of points connected by line segments. 

Almost as suggestive as violin plots are the paintings by {{w|Georgia O'Keeffe}}, an American painter known for her {{w|Flower paintings of Georgia O'Keeffe|paintings of flowers}}. Some of these flowers, ''{{w|Black Iris (painting)|Black Iris}}'' for example, are said to symbolize female genitalia, though O'Keeffe herself denied those claims.

The title text invokes the fact that many people incorrectly use the word "{{w|vagina}}", which refers to an internal structure, for the {{w|vulva}}, which is the external portion of the female genitals. Meanwhile the {{w|viola}} is an instrument often mistaken for a {{w|violin}}. And the word "viola" shares common letters with "vulva." Mixing pedantic terms like this was also used in [[1405: Meteor]].

[[Randall]] has made several comics with [[:Category:Sex|sexual topics]], and the vagina has been the center of attention before, as early as in [[136: Science Fair]]. There is even an entire [[:Category:Penis|Penis category]]. However, these topics haven't appeared recently — the last comic in the penis category was posted more than two years ago, and the sex category hasn't had a new comic since December 2017 (more than three months before this comic).

Nothing is rarely a coincidence in Randall's comics, so the reason that pie charts are included, could be that this comic was released on {{w|Pi Day}}. Randall has shown facination with Pi in earlier comics like [[1292: Pi vs. Tau]]. On the other hand the reason they are included could be that we know from the movie {{w|American Pie (film)|American Pie}} that putting a finger in such a pie feels like putting it inside a {{w|Vagina|Violin}}... It could of course be both reasons, or none of them...

==Transcript==
:[Header over a violin plot type chart:]
:Suggestiveness of different visualization types

:[The chart only has an Y-axis with tics, ranking the points on the plot. There are legends at the top and at the bottom:]
:Suggestive
:Not very suggestive

:[There are four points on the graph, each with a mucosa colored and "violin" shaped probability density around each point. The points are white inside a black box plot like structure with black error bars. The two first points to the left are very low near the bottom of the Y-axis while the two next point to the right are almost at the top of the chart, the last also clearly with the probability density higher than the second last. Above the first two and below the second two points there are legends:]
