To make the right choice, consider what type of data you need to convey, and to whom it is being conveyed. The right chart will not only make the data easier to understand, but also present it in the most accurate light. Deciding what type is best for visualizing the data being presented is an art unto itself. There are so many different types of charts. Use Visual Features to Show the Data Properly Take into account how familiar the audience is with the basic principles being presented by the data, as well as whether they’re likely to have a background in STEM fields, where charts and graphs are more likely to be viewed on a regular basis. It should be compatible with the audience’s expertise and allow viewers to view and process data easily and quickly. Know the AudienceĪ data visualization is useless if not designed to communicate clearly with the target audience. Taking time at the outset of a data visualization project to clearly define the purpose and priorities will make the end result more useful and prevent wasting time creating visuals that are unnecessary. It can be used to track performance, monitor customer behavior, and measure effectiveness of processes, for instance. By turning complex numbers and other pieces of information into graphs, content becomes easier to understand and use.ĭata visualization should answer vital strategic questions, provide real value, and help solve real problems. That’s why data visualization plays an important role in everything from economics to science and technology, to healthcare and human services. Data visualization designers can play a vital role in creating those abstractions.Īfter all, big data is useless if it can’t be comprehended and consumed in a useful way. IDC predicts there will be 175 zettabytes of data by 2025.Īll of this data is hard for the human brain to comprehend-in fact, it’s difficult for the human brain to comprehend numbers larger than five without drawing some kind of analogy or abstraction. The Research Scientist Andrew McAfee and Professor Erik Brynjolfsson of MIT point out that “more data cross the internet every second than were stored in the entire internet just 20 years ago.”Īs the world becomes more and more connected with an increasing number of electronic devices, the volume of data will continue to grow exponentially. According to IBM, 2.5 quintillion bytes of data are created every day.
