What is Density chart?

A density chart, also known as a density plot or kernel density estimate (KDE), is a visualization that represents the distribution of a dataset by displaying the probability density function of a continuous variable. It smooths out the data points into a continuous curve, allowing for easier interpretation of data trends and patterns, especially in large datasets. Unlike histograms, density charts do not rely on binning, which can lead to artifacts based on bin width; instead, they provide a more nuanced view of the underlying distribution. Density charts are commonly used in statistical analysis and data exploration to identify areas of concentration and to compare distributions.
