What is data visualization? Presenting data for decision-making Leave a comment

For those more complex datasets, there are a range of more elaborate data visualizations at your disposal—network graphs being one of them. Network graphs show how different elements or entities within a network relate to one another, with each element represented by an individual node. Both types of visualizations generally require software to create, as the most effective visualization will draw from several data sources. Whereas data scientists do most of the work on visual exploration, managers do most of the work on everyday visualizations. This quadrant comprises the basic charts and graphs you normally paste from a spreadsheet into a presentation.

Network graphs are great for spotting and representing clusters within a large network of data. Let’s imagine you have a huge database filled with customers, and you want to segment them into meaningful clusters for marketing purposes. You could use a network graph to draw connections and parallels between all your customers or customer groups. With any luck, certain clusters and patterns would emerge, giving you a logical means by which to group your audience.

It depends on the organizational culture and how much data-driven decision-making is valued,” says Ferenczi. While Microsoft Excel is useful for many things, big data visualization isn’t one of them. There is a limit to how much data Excel can store, which means it might not be appropriate for all use cases. These functional areas tend to have a lot of data available, and it’s beneficial to see the impact teams’ efforts are having across channels and in different geographic areas. Discovering a channel that’s under- or over-performing gives leadership the signal to investigate further and identify a potential gold mine or deadweight. For example, a company may conduct a study on employee engagement and use an infographic to walk through numerous stats from the study in visual form.

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. Better hardware has meant more precise reproduction, better color (including alpha-blending), and faster drawing. Better software has meant easier and more flexible drawing, consistent themes, and higher standards. Computer scientists have become much more involved, both on the technical side and in introducing new approaches.

At its core, data visualization is the process of making raw data and information visible and understandable for people. This can be as simple as plotting a bar chart in your regular spreadsheet tool, or it can be as complex as a dynamic infographic. Data visualization helps deliver a message, rather than just sharing the data without any clear messaging. With data visualization tools, you can generate to-the-point visual reports that encapsulate valuable business insights and complex data through a series of graphs and charts.

The experts who write books and teach classes about the theory behind data visualization also tend to keep blogs where they analyze the latest trends in the field and discuss new vizzes. Many will offer critiques on modern graphics or write tutorials to create effective visualizations. Others will collect many different data visualizations from around the web in order to highlight the most intriguing ones. Blogs are a great way to learn more about specific subsets of data visualization or to look for relatable inspiration from well-done projects. The best data visualization tools include Google Charts, Tableau, Grafana, Chartist.js, FusionCharts, Datawrapper, Infogram, ChartBlocks, and D3.js.

Getting the Big Picture With Data Visualization

We know we give pie charts a hard time, but that’s only because there are so many more options to choose from. From Gannt charts, to chord graphs, to sunbursts, and more — different charts make it easier to perform different kinds of analysis. That graph or chart that you’re thinking of, is a perfect example of a data visualization. From that graph, you might be able to infer increasing performance or different trends. Without the graph, these same sorts of analyses would be much harder to determine.

If you’re a larger organization that needs to integrate marketing data with a robust business intelligence department, you may want to opt for something like Tableau. If you’re a smaller organization or agency that needs to perform monthly marketing reporting, Google Data Studio may be a great solution. Plus, we designed a set of free dashboard templates that you can use in Data Studio yourself. We knew that the visualization was going to have a diverse array of “data,” and an infographic is a fun way to present that type of information. For instance, a data scientist will have a much more detailed and technical approach to the subject than a marketer. That data scientist may want to explore margins of error or perform complex statistical analysis.

Geo maps are used to visualize the distribution of data in relation to a physical, geographical area. For example, you could use a color-coded map to see how natural oil reserves are distributed what is big data visualization across the world, or to visualize how different states voted in a political election. Maps are an extremely versatile form of data visualization, and are an excellent way of communicating all kinds of location-related data. Some other types of maps used in data visualization include dot distribution maps , and cartograms which distort the size of geographical areas to proportionally represent a given variable .

Effective data visualization makes data analysis easier

When dealing with data sets that include hundreds of thousands or millions of data points, automating the process of data visualization makes a designer’s job significantly easier. Data visualizations can be used to discover unknown facts and trends. You may see visualizations in the form of line charts to display change over time. Bar and column charts are useful when observing relationships and making comparisons.

Polymaps is a good option if maps are the only type of visualization required, as long as the designer is comfortable with some basic coding.

Dashboards come in handy when you want to summarize a lot of data in visual form for different audiences and monitor it over time. A pie graph is used to show how different parts make up a whole. Each wedge represents a different item or segment, and all the wedges add up to a total (e.g., 100 percent). You can use a pie graph to visualize, for example, what segment of website visitors are using Chrome vs Firefox vs Internet Explorer.

“It doesn’t matter how cool your charts are if they aren’t accurate,” says Ferenczi. For your visuals to have value, the underlying data must be of high quality. Otherwise, you’ll be presenting visually impressive graphs and charts that, at best, don’t provide many insights.

The executive can then take action to solve the problem and achieve her goal. You may collect data about, say, your variable costs, and identify a specific expense that needs to be addressed. Simply presenting the executive with the tables of data won’t assist in the decision-making process because this will require significant time and energy to absorb. This chapter takes a deeper dive into data visualization, putting it into different industry contexts with distinct use cases.

Simplicity like this takes some discipline—and courage—to achieve.
