What is Data Visualization ?????

                                           

        The data visualization is another growing and vast field in era where the most valuable resource on the earth is no longer the oil but the data. The visualization is the of representing a data or information in a form of pictures, charts, images, graphs, etc. Visualizing is more about the picturing the situation based on the available data. 

        

                            "The Purpose of Data Visualization is insight, not pictures"

                                                                                                            - Ben Schneiderman 

            The Visualization makes the understanding of the data much easier for humans. Visualization is also acts like a story telling which makes the understand the data and patterns much easier. This thing makes the decision making process faster. A human perception system mainly works on the visual information. Human brain naturally looks for the stories in the visual context.

Example: 

The picture below is a raw csv file indicating the total covid-19 cases by state in the united states. This file just show the numbers which does not make any story or visual perception.

Link for csv file: https://raw.githubusercontent.com/nytimes/covid-19-data/master/live/us-states.csv

Where as the below picture is the visualization of the data in a csv file above as we discussed the visual pictures tell us more about the data and makes the perceptions easier from below visualization it makes easy to understand the outbreak of covid-19 in the united states and also this indicates the states which are going through the severe stage of this outbreak.
