A density plot is a data visualization tool that represents the distribution of a dataset. It is a smoothed version of a histogram, created using Kernel Density Estimation (KDE). The plot shows the probability density function of the data, with higher peaks indicating regions with more data points.
Creating Density Plots in Python
Using Pandas
Pandas provides a simple way to create density plots using the plot.density() or plot.kde() methods. Here is an example using the car_crashes dataset from the Seaborn library:
import pandas as pdimport seaborn as snsimport matplotlib.pyplot as plt# Load the datasetdata = sns.load_dataset('car_crashes')# Plot the density plot for the 'speeding' attributedata.speeding.plot.density(color='green')plt.title('Density plot for Speeding')plt.show()In this example, the density plot shows that the most common speed for car crashes is between 4-5 km/h, as indicated by the highest peak1.
