Seaborn Heatmap Hindi: lesson notes

1. 01Previous Plots Recap

   • Relational Plot

     • Scatter, Line, Relplot

   • Distribution Plot

     • Histplot, KDEplot, ECDFplot, Displot

   • Categorical Plot

     • Countplot, Barplot, Boxplot, Violinplot, Stripplot, Catplot

   • Regression Plot

     • Regplot (Axes-level)
     • Implot (Figure-level)

2. 02Heatmap

   • Purpose

     • Visualize correlation between numerical variables
     • X increases, Y increases (positive correlation)
     • X increases, Y decreases (negative correlation)

   • Basic Usage

     • Import libraries (numpy, pandas, matplotlib, seaborn)
     • Create sample data
     • sns.heatmap(data, annot=True, cmap='Blues')
     • plt.show()

   • Parameters & Interpretation

     • annot=True shows values
     • cmap sets color scheme
     • fmt='.2f' formats values
     • Correlation values range from +1 to -1
     • +1 is strong positive (dark red)
     • -1 is strong negative (dark blue)
     • 0 is no correlation (light color)
