There is no doubt one of essential concept in data exploration and analysis is
visualization of the data. Data visualization is the presentation of data in a pictorial or graphical
format, thus enabling the decision makers to visualize the data and make informed decision [1].
Notably, large data is generated regularly, which needs extensive analysis and interpretation. As
a result, there are various benefits associated with the data visualization to various sectors (data
analysts (decision makers) and organizations). For example, the concept aids in including
enhanced assimilation of business information, whereby many business intelligence reports
incorporate numerous visualization tools, such as statistics tables and charts [2]. Moreover,
business managers in organization that utilize visual data tools are 28% more likely to find
timely information than those who depend solely on managed reporting and dashboards.
Besides, data visualization aids in rapid identification of latest trends, whereby
companies are able to gather various business insights, such as revenue, expenses, and business
opportunities thus make informed decision [3]. For instance, the decision makers are bale to
identify shifts in the customer behavior and market conditions. Furthermore, data visualization
plays a critical part in predictive analysis of various sections, such as sales whereby decision
makers can forecast the increase or decrease of sales. Therefore, the following study will use of
data visualization to exhibit insights and characteristics of real GDP data in the United states
collected quarterly.
There are various tools used in data visualization, which include line graph, bar chart, pie
chart, scatter plots, and histogram [3]
Bar graphs: They are used to exhibit comparison among individual items; for instance,
the graph can be used it the study illustrate gender comparison, whereby the graph will show
between male and female which gender recorded higher sales.

Pie charts: They are used to illustrate the contribution of individual measurement value to
the grand total represented in a circle.
Histogram charts: They are charts used to show the frequency of an event. Thus, the
following chart exhibits the frequency distribution of services provided.
