How can the size of cells in a Seaborn heatmap be reduced?

edit

To reduce the size of cells in a Seaborn heatmap, you can adjust the heatmap's linewidths parameter. This parameter is used to specify the width of the lines that separate each cell in the heatmap. By setting the linewidths parameter to a smaller value, you can reduce the size of the cells in the heatmap. Here's an example code snippet:

import seaborn as sns
import matplotlib.pyplot as plt

# Load the example tips dataset
tips = sns.load_dataset("tips")

# Create a heatmap
sns.heatmap(
    tips.corr(),
    cmap="coolwarm",
    annot=True,
    linewidths=0.1 # Set the linewidths to 0.1 to reduce cell sizes
)

# Show the plot
plt.show()

In the above code, we create a heatmap using the sns.heatmap() function from Seaborn, and we set the linewidths parameter to 0.1 to reduce the size of the cells in the heatmap. You can adjust this value as needed to achieve the desired cell size.
