Unlike a box plot, in which all of the plot components correspond to actual datapoints, the violin plot features a kernel density estimation of the underlying distribution. Violin plots are used to visualize data distributions, displaying the range, median, and distribution of the data. A Violin plot is an abstract representation of the probability distribution of the sample. 12, Apr 20.
