10 Python Libraries for Data Visualization

With over 8.2 million active users, Python has grown to be the most widely used language in the world. Frontend, backend, data science, machine learning, artificial intelligence, middleware, deep learning, etc., are a few applications for which Python can be used.

Besides its wide applications and ease of use, the supportive community of millions of experts makes it a top choice for beginners. Below are some python learning libraries that every data analyst and scientist should know.


Pandas library in Python is one of the useful libraries for the easy-to-use data structure for analysis and handling. It provides efficient, fast, and optimized objects, especially for data manipulation tasks. The open-source and data science communities make Pandas the suitable data library. In addition, the rich functionalities of Pandas help you deal with missing data or create your own data.


TensorFlow is a framework best known for data visualizations and computational graph visualizations. It reduces 50-60% of errors in data using neural machine learning models. The python data libraries collect data that are available and are useful to train and deploy machine learning models for production.


Machine learning is a branch of data science used for predictive data analysis. It is an accessible, reusable, open-source package built on SciPy, Matplotlib, and NumPy.

The widely-used library that data scientists use helps them in data storage, regression, classification, and clustering with basic machine-learning algorithms.


Another open-source python data science library in our list is SciPy, which is useful in simple data science and analytics projects for optimization and integration. The high-level solutions provided by SciPy help in underlying mathematics, linear algebra equations, statistics, and differential equations for data science projects. The in-built collections of the algorithm are used in data science for manipulating data visualization components or layers to ease scientific calculations.


Like other tech fields, data science and the use of data structures are constantly evolving, and the need for data analysis and manipulation tools is rising. As a result, scientists need a simple supervised and unsupervised machine learning approach to move from research to practice. The PyTorch library helps data scientists quickly shift from theory to machine learning research.


In data science and machine learning, algorithms, tasks, and structured data visualization play a considerable role. Matplotib is one of the useful Python data visualization libraries that provide plots and figures developers can utilize for data visualization creation. However, the primary function of the open-source plotting library for Python is to bring different types of data between in-memory data structures to life and uncover insights to solve many data science problems.


Many data mathematics complications make it hard for data scientists to solve mathematical operations. The use of the data in the library helps you to solve problems related to data processing, mining, and wrangling. One of the useful open-source python libraries for data aggregation and creating a python object is Theano, which is also useful in creating web-based data visualizations and evaluate multi-dimensional expressions.


Keras library supports Theano and Tensorflow backends and is useful for data analysis, deep learning, and neural network modules. It offers vast prelabeled data sets which you can import and load. Using the popular Python library will help developers reduce cognitive load. It also minimizes the actions used for data visualization.


One of the most useful statistical data exploration libraries is NumPy, or Numerical Python library contains a powerful N-dimensional array object. Developers can use NumPy in data analysis for faster and more compact computations. In addition, the general-purpose array-processing package of libraries like NumPy provides interactive data visualization to improve efficiency.


The next known library for data in Python that enables quick and easy data manipulation is Scrapy. It is a popular open-source and fast web crawling framework written in Python. Data professionals use Scrapy data science libraries to build crawling programs, collect, and retrieve structured data from the web. Developers can train machine learning models using libraries and tools for better data analysis.
