If you have to explain them, then you failed. Test Visualization Forms: Visualizations are like jokes. Limit the number of visualizations in dashboards and reports.ĥ. Deliver the information in a precise and short narrative so the viewer stays engaged and remembers what they learned. Plan to Prevent User Fatigue: Too many visualizations tire the viewer out, as do unfamiliar depictions or overly complex graphics. Make sure you're telling the story you meant to tell.Ĥ. Everything in every visualization is telling a story. But do the bars correctly relate to one another or is the scale off? Details matter. Pay Attention to Every Detail: So you'd like the bar graph in this BI app to convey this piece of information. Your goal is to produce easy-to-read visualizations even if the content is anything but.ģ. Make Clarity Your Top Priority: Be clear and be concise, even with highly detailed and complex information. Pick a visualization that will deliver the detail and context they need to act on the information, without having to sort through a seemingly endless pile of related visualizations.Ģ. But don't skimp on information if you're conveying it to an audience steeped in statistical, data science, engineering, or other top-shelf skills. So, if funny hotdogs in an infographic depict your sidewalk vendor sales best, go with that. Know Your Audience: Pick a visualization your audience is most likely to find relatable and engaging. You can create these in Microsoft Excel, for example. Sunburst Chart: Also called multi-level pie charts, these are primarily used to visualize hierarchal data using concentric circles. You'll find more in-depth information on Arc Diagrams in this paper by IBM Research.Ģ. Think DNA and streaming data from the Internet of Things (IoT). Arc Diagrams: These diagrams are uniquely capable of representing complex patterns in string data, meaning sequences that often also contain repetitive subsequences. Here's a short description of some of the visualizations in this category worth considering and where you'd want to use them:ġ. However, you'll find many audiences already familiar with these more exact metrics and data representations, including statisticians, engineers, and many professionals working in the sciences.
However, it is well worth it if you need to regularly convey more than generalized information and don't want to pull a van Gogh.

It may take some effort to teach your audience how to read some of the more sophisticated visualizations. In any case, you know these visualizations already. The message is lost on the mind that wanders. Further, the use of too many visualizations can cause user fatigue. That's neither efficient nor instructive. In dashboards and reports, all of those added visuals can pile up and, by the time your audience gets to the end of the heap, they've forgotten how that information relates to the first or other visuals in the pile. Perhaps a sign that reads "No right turn on red" or perhaps you'll add another stoplight just for the turn lane. If you want to say something else, then you have to add another visual. A traffic light is reduced to three features because there are only three messages to convey: go, slow down, and stop.

So why wouldn't you stop here and pick one of these? Or, as is an option in many BI apps, let the software pick one for you?īecause not every analytic output can or should be expressed in such an over-simplified conveyance. Indeed, their very familiarity means your audience doesn't have to stop and figure out the form before they can understand the message. They have been in use for a long time for good reason: they work. There is nothing wrong with this group of visualizations. Modern data visualizations take that powerful communication medium to an entirely new level, infusing the rich charts and graphs generated with rich data. One glance at picture-based messages and the information is understood no matter your language or math skills. History shows us the concept has been successfully tested over time, from early cave drawings to modern universal traffic signs recognized all over the world regardless of language. This human penchant for pictures over numbers is far from a recent discovery. That one factor heavily outweighs any argument in support of spreadsheets for one simple reason: Human brains absorb and process visual representations of information faster and better than they do numbers. There are many reasons these tools are superior to a spreadsheet, but the most obvious is the capability to easily produce effective and compelling data visualizations. However, most businesses today have moved past the fleeting pull of nostalgia in favor of more powerful self-service business intelligence (BI) tools. Spreadsheets have been a mainstay in business for so long that some people have trouble letting them go. Best Malware Removal and Protection Software.
