What is Data Visualization??

• Data visualization is the representation of data
  or information in a graph, chart, or other visual
  format. It communicates relationships of the data
  with images. This is important because it allows
  trends and patterns to be more easily seen. With
  the rise of big data upon us, we need to be able
  to interpret increasingly larger batches of data.
  Machine learning makes it easier to conduct
  analyses such as predictive analysis, which can
  then serve as helpful visualizations to present.
  But data visualization is not only important for
  data scientists and data analysts, it is
  necessary to understand data visualization in any
  career. Whether you work in finance, marketing,
  tech, design, or anything else, you need to
  visualize data. That fact showcases the
  importance of data visualization.

Importance of Data Visualization

• We need data visualization because a visual
  summary of information makes it easier to
  identify patterns and trends than looking through
  thousands of rows on a spreadsheet. Its the way
  the human brain works. Since the purpose of data
  analysis is to gain insights, data is much more
  valuable when it is visualized. Even if a data
  analyst can pull insights from data without
  visualization, it will be more difficult to
  communicate the meaning without visualization.
  Charts and graphs make communicating data
  findings easier even if you can identify the
  patterns without them. Without a visual
  representation of the insights, it can be hard
  for the audience to grasp the true meaning of the
  findings.
