Seaborn = statistical data visualization library built on Matplotlib.
Makes beautiful plots with less code, better defaults.
Install: pip install seaborn
Import: import seaborn as sns
Works best with Pandas DataFrames.
sns.scatterplot(data=df, x="sepal_length", y="petal_length", hue="species")
sns.histplot(data=df, x="age", kde=True)
sns.boxplot(data=df, x="species", y="petal_length")
sns.heatmap(df.corr(), annot=True, cmap="coolwarm")
sns.pairplot(df, hue="species")Used in ML: pairplot to see feature relationships.
