**Data Science:** Data science is study of data. It involves developing methods of recording, storing, and analyzing data to extract useful information. The goal of data science is to gain knowledge from any type of data both structured and unstructured. Data science is a term for set of fields that are focused on mining big data sets and discovering trends, methods, new insights, and processes. It works on any size of data. Some of the applications of data science are E-commerce, Manufacturing, banking, health care, transport, finance, etc. Data science is a “concept to data analysis, machine learning, and unifies statistics” in order to understand actual phenomena with data.

**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 analyze massive amounts of information and make data-driven decisions. The concept of using pictures to understand data has been used for centuries. General types of data visualizations are Charts, Tables, Graphs, Maps, Dashboards.

Below is a table of differences between Data Science and Data Visualization:
