Figure 4.
In the density plot, each individual density plot shows the distribution of values for one of the variables in our dataset. The x-axis shows the values that the variable can take, and the y-axis shows the estimated probability density for each value. The plot is split into two colors (blue and red) corresponding to the two possible values for the isMut output column (0 and 1). The darker the color, the higher the density of points in that area.
