Data-Visualization-using-python

This repository contains data visualization programs on various datasets done using python.

Data Visualization

--> Data visualization is the graphical representation of information and data in a pictorial or graphical format(Example: charts, graphs, and maps).

--> Data visualization tools provide an accessible way to see and understand trends, patterns in data, and outliers.

--> Data visualization tools and technologies are essential to analyzing massive amounts of information and making data-driven decisions.

--> The concept of using pictures is to understand data that has been used for centuries. General types of data visualization are Charts, Tables, Graphs, Maps, Dashboards.

Various forms of Data Visualization

About Python Programming

--> Python is a high-level, general-purpose, and very popular programming language.

--> Python programming language (latest Python 3) is being used in web development, Machine Learning applications, along with all cutting-edge technology in Software Industry.

--> Python is available across widely used platforms like Windows, Linux, and macOS.

--> The biggest strength of Python is huge collection of standard library.

Mode of Execution Used

--> Colaboratory, or “Colab” for short, is a product from Google Research which allows anybody to write and execute python code in Jupyter notebook through the browser.

--> Visit colab at:

--> Create account using google account.

--> Once account creation is done, we can directly start coding in colab.

--> It supports Python and R.

--> Files are directly saved in Google Drive.

--> It contains the following dimensions-[457 rows X 9 columns].

--> The csv file is already preprocessed ,thus their is no need for data cleaning.

Libraries Used

Short Description about all libraries used.

NumPy (Numerical Python) – Enables with collection of mathematical functions to operate on array and matrices.
Pandas (Panel Data/ Python Data Analysis) - This library is mostly used for analyzing, cleaning, exploring, and manipulating data.
Matplotlib - It is a data visualization and graphical plotting library.
Seaborn - It is an extension of Matplotlib library used to create more attractive and informative statistical graphics.
SciPy (Scientific Python) - used for scientific computation. SciPy contains modules for optimization, linear algebra, integration, interpolation, special functions, FFT, signal and image processing
Scikit-learn - It is a machine learning library that enables tools for used for many other machine learning algorithms such as classification, prediction, etc.
Geopandas-GeoPandas, as the name suggests, extends the popular data science library pandas by adding support for geospatial data.
