A density plot is a graphical representation used to visualize the distribution of a continuous variable. It shows the probability density function of the variable, allowing viewers to see where values are concentrated. Unlike a histogram, which uses bars to represent frequency, a density plot uses a smooth curve, making it easier to identify patterns and trends in the data. Density plots are particularly useful in statistics and data analysis, as they can reveal the underlying distribution shape, such as whether it is normal, skewed, or multimodal. They are often used in conjunction with other visualizations, such as box plots or scatter plots, to provide a comprehensive view of the data's characteristics.
