Hello,
Today’s world is a world of big data. Big data means lots
and lots of data. To understand this data, one needs to analyze it and to make
it understand to people who are not related to the data, one needs to present
it. Hence, data visualization has gained prime importance in conveying
information to people. Complex problems can be understood by data visualization
as it shows how different data are related to each other. Data visualization is the presentation of data in
a pictorial or graphical format. It enables decision makers to see analytics
presented visually, so they can grasp difficult concepts or identify new
patterns.
Following are some of the examples of data visualization
techniques in different lines of business:
1. Healthcare
The above graph has different colors for different countries
and every country’s data in a certain age bracket. This is an excellent way to
represent data as it gives us the distribution country wise, age wise and cost
wise, all in one graph.
2. Technology
The above dashboard shows different ways in which the sales
can be depicted. The bar graph very conveniently shows both the sales and the
goals for that month. It makes it very easy to compare the sales to goal
ration. The map is used to depict sales by region with the color indicating
density. A simple pie chart is used to show the sales breakdown by product since
only percentages matter here.
3. Customer relationship management
This is an excellent dashboard showing the CRM functions.
The bar graph shows a good comparison of different types of customers in
different periods. Pie chart shows the cases by subject. The line graph shows
how the number of open and resolved cases increase or decrease every month. It
gives us a trend.
In conclusion, visualization transforms data into information.
