Music effects on depression
In this exercise, your task is to create a density plot that illustrates the impact of music on the depression levels of survey respondents. You will visualize the results by grouping them into categories: those who claim music helps, those who report no effect, and those who claim it worsens their condition.
The Plots
package has already been loaded for you, and the streaming
DataFrame is readily available.

Exercise instructions
- Customize the density plot setting the line width to be
4
and the line styles to:solid
,:dash
, and:dot
in that order. - Give the legend the title
"Music effect"
and position it on the:bottom
. - Limit the x-axis values to range from
0
to10
.
