- Data visualization is used in many disciplines and impacts how
we see the world daily. It’s increasingly important to be able to
react and make decisions quickly in both business and public
services. We compiled a few examples of how data visualization is
commonly used below.
According to research by the media agency Magna, half of all
global advertising dollars will be spent online by 2020. Because of
this, marketers need to stay on top of how their web properties are
creating revenue along with their sources of web traffic.
Visualizations can be used to easily see how traffic has trended
over time as a result of marketing efforts.
Finance professionals need to track the performance of their
investment choices to make decisions to buy or sell a given asset.
Candlestick visualization charts show how the price has changed
over time, and the finance professional can use it to spot trends.
The top of each candlestick represents the highest price within a
period of time and the bottom represents the lowest. In the
example, the green candlesticks show when the price went up and the
red shows when it went down. The visualization can communicate the
change in price more easily than a grid of data points.

- Who is the audience, and how will it read and interpret the
information? ...
- What are viewers' expectations, and what type of information is
most useful to them?
- What is the visualization's functional role,
and how can viewers take action from it?

- Linear Regression is a very powerful statistical technique and
can be used to generate insights on consumer behaviour,
understanding business and factors influencing profitability.
Linear regressions can be used in business to evaluate trends and
make estimates or forecasts. For example, if a company’s sales have
increased steadily every month for the past few years, by
conducting a linear analysis on the sales data with monthly sales,
the company could forecast sales in future months.
- Linear regression can also be used to analyze the marketing
effectiveness, pricing and promotions on sales of a product. For
instance, if company XYZ, wants to know if the funds that they have
invested in marketing a particular brand has given them substantial
return on investment, they can use linear regression. The beauty of
linear regression is that it enables us to capture the isolated
impacts of each of the marketing campaigns along with controlling
the factors that could influence the sales. In real life scenarios
there are multiple advertising campaigns that run during the same
time period. Supposing two campaigns are run on TV and Radio in
parallel, a linear regression can capture the isolated as well as
the combined impact of running this ads together.
- Linear Regression can be also used to assess risk in financial
services or insurance domain. For example, a car insurance company
might conduct a linear regression to come up with a suggested
premium table using predicted claims to Insured Declared Value
ratio. The risk can be assessed based on the attributes of the car,
driver information or demographics. The results of such an analysis
might guide important business decisions.
