Making Heatmap from Pandas Dataframe

Given a Pandas DataFrame, we have to make heatmap from it.

Pandas is a special tool that allows us to perform complex manipulations of data effectively and efficiently. Inside pandas, we mostly deal with a dataset in the form of DataFrame. DataFrames are 2-dimensional data structures in pandas. DataFrames consist of rows, columns, and the data.

Data visualization is a process of representing the data in the form of graphs, plots, and other pictorial formats for better understanding of data and effective analysis of data.

To make a heatmap from pandas DataFrame, we need to install the seaborn library. We will use seaborn.heatmap() method to make a heatmap.

To work with pandas, we need to import pandas package first, below is the syntax:

import pandas as pd

Let us understand with the help of an example,

Python code to make heatmap from pandas Dataframe

# Importing pandas package
import pandas as pd

# Importing seaborn as sns
import seaborn as sns

# Creating a dictionary
d = {

# Creating a DataFrame
df = pd.DataFrame(d)

# Creating heapmap
heap = sns.heatmap(df)

# Display heap
