Like Data Analysts, Data Visualization Engineers usually attain their undergraduate degrees in subjects that rely heavily on statistics and analysis, including Math, Statistics, Computer Science, Business Management, Finance or Economics.
Data Visualization Engineers also need a solid understanding of user interface (UI) development so that they’re able to create defined data visualization elements, in addition to the application and data services required to apply those elements to the specific query. This is why many of them pursue additional skills to help them specialize in their chosen field.
Data Visualization Engineers focus on the design and development of reporting solutions that best convey the results to their clients. They help identify patterns, trends and changes in the data that may be otherwise hidden or not readily apparent by stand-alone numbers and text.
That’s why they walk the line between the technical and the creative. Technically, they must be able to understand what the data reveals in comparison to the client’s goals before they’re able to create a visual representation of it; and in order to translate the facts and figures into a valuable insight, a creative focus becomes crucial.
For example, a simple graph may show peaks and valleys, but it may not highlight some of the less dramatic nuances. Those finer details may be essential to understanding how the highs and lows develop, and an important focus of the report.
Creatively, Data Visualization Engineers need to know how their clients will best respond to the visual analysis. They must be able to interpret and express what the data means, know what colors and shapes to use, and be able to compile the information in such a way that viewers instinctively can interpret what it all means when compiled.
SQL (structured query language) is the foundation of complex queries because most big data systems use it, along with additional proprietary extensions for more customized use.
Even so, the standard SQL commands such as "Select," "Insert," "Update," "Delete," "Create" and "Drop" can still be used to accomplish most tasks – a universal language to master.
Descriptive Analytics requires Data Visualization Engineers to communicate their findings in an illustrative way;
In order to do so, they need to be familiar with the wide assortment of tools that are at their disposal.
D3.js is at the top of the list for Data Visualization Engineers, because it allows them to showcase data findings from HTML, SVG, and CSS and it provides all of the selected browser functionality without having to adhere to its framework.
D3’s data-driven approach combines with powerful visualization components, allowing Data Visualization Engineers to bind arbitrary data to a Document Object Model (DOM), and then apply the indicated data transformations to the document.
ggplot2 allows Data Analysts to plot trends on a graph with unique color-coding to help distinguish between key points. The findings can then be processed directly as a PDF or object that can be easily disseminated to shareholders.
Tableau is an essential software package that can present the data and showcase the derived insights. It provides a wide array of tools that allow Data Analysts to drill down further and see the results in a variety of visual formats.
Illustrator shouldn’t be overlooked, either, as it can be a great assist for Data Visualization Engineers. It’s a vector-based, graphic software that is used to develop images. Its versatility is what makes it so valuable across many business applications.
What salary can a Data Visualization Engineer expect? Like any position, it depends on the level of experience, the amount of additional training and certifications attained and the demonstrated ability to work well with others. According to the experts, Data Visualization Engineers make:
