A density plot shows the **distribution** of a numerical variable. It takes only set of numeric values as input. It is really close to a histogram. Since it is a really common dataviz technique,

most of the dataviz libraries allow to draw it. Note that it is highly recommended to play with the bandwith argument in order not to miss a specific pattern in the data. Note that you can compare the

distribution of **several variables** plotting them on the same axis, using faceting or through a joyplot.

**Input format**

To represent a density, you need only **one vector of numbers**. It can be a list, or the column of a data frame.

If you have several numerical variable, you can plot several densities and compare them, or do a boxplot or violin plot.

*Format 1*: 1 numerical variable only.
