Data Visualization Making Sense of Big Data
In 2017 The Economist published an article with the header: The World’s Most Valuable Resource is no Longer Oil, but Data. Data in its raw form isn’t valuable, however. It’s not until it is made intelligible and can be used to see patterns and make predictions that its value is realized. And this is where data visualization is playing a growing role.
Data visualization is a simple but powerful tool that has the ability to cut through complex amounts of data analysis in a succinct, manageable way by graphical representation. According to an article on data visualization, a large part of the human brain is devoted to vision— “as much as 80% of sensory input is processed by the visual pathway.” Using this vital sense we can more easily interpret data, making its conclusions more quickly and easily accessible.
Our human eyes are drawn to colors and patterns and this in turn can help us more quickly comprehend information. The visual organization of graphs or charts can neatly display in a small space what might take pages and pages to communicate in words. In a research study, graphic organizers such as charts or graphs, improved student performance in retention, reading comprehension, thinking and learning skills and critical thinking. But conveying large amounts of data in a two dimensional sphere is challenging and has to be done well to be effective. That’s where the 5 step model comes in.
Creating good data visualization material from start to finish requires organization and can be broken down into 5 steps:
Let’s take a look at a few graphic depictions of information that are well executed.
We’ll start with a famous illustration that mastefully depicts six types of data in two dimensions. The historical graph depicts Napoleon’s army departing the Polish-Russian border and their advances and retreats to Moscow. The Napoleonic army’s size is also displayed at various geographic points. This particular graph displays six types of data in two dimensions: the number of Napoleon’s troops; distance traveled; temperature; latitude and longitude; the direction of travel; and location relative to specific dates.
Another beautiful example is the near-floral visualization that interactively looks at the US Trade Deficit from 2001 – 2013 by month. The moving visual shows the top 20 trading partners for both imports and exports. This graph was created with publicly available information.
Lastly, The graph below details gun deaths in 2013 and the approximate number of years lost per individual in each tragic gun death. It’s clearly impactful as each line represents a life lost.

In our current day and age, Big Data is growing both in its volume and its usages. More and more we are storing and gathering data from vast pools of information. Data Visualization is an increasingly important tool to make sense of and manage the trillions of rows of data generated every single day. With the massive amount of data being generated, communicating this information is getting difficult. But data visualization is coming to the rescue.
Let’s take, as an example the healthcare industry who deals with incredible amounts of data in its search to ameliorate human health. Health organizations have begun to create custom graphs and charts for data. These visualizations are also interactive according to the data that the client wishes to see. You can see a sample chart here. The chart allows you to input data searching for patterns and trends and can be searched by both cause of death and risk. It’s a quick and impactful way to communicate to patients information about their particular health situation.
In cases with large amounts of data, with just a few key details being communicated, data visualizations are ideal. This is often the case when looking at healthcare on a state-by-state level or a local versus federal level where the information of interest is only a small part of a bigger picture. As an example, see this interactive visualization on child vaccinations in America.
Data visualization helps to tell stories by curating data into a form that is simplified and easy to digest. This has become all the more important with the rise of Big Data. With so much data available, it is critical to be able to succinctly and rapidly communicate specific information. Graphical representations are becoming one of the primary communicators across industries for their ability to easily highlight trends and outliers.
