Data visualization: Six tips to build a perfect dashboard

Dashboard Oldtimer

In the age of big data, business intelligence and artificial intelligence, data plays an increasingly important role for companies. Dashboards are now widely used, bringing data to the point and thus becoming an important basis for decision-making.

But the optimal visualization of data still is a challenge. With the following six tips you will be able to build a great dashboard and save time.

1. Have a clear goal in mind

What sounds trivial is a common reason for overburdened and meaningless dashboards. First of all, ask yourself the following questions:

  • What do you want to achieve with your dashboard?
  • Who is the target audience for the dashboard?
  • What data do you need to display to get your target audience attracted?

It makes a huge difference whether you create a dashboard for your finance department, consumer research or marketing team. Although the database may be the same, users’ interests and priorities can vary a lot. Market researchers usually want details and with many drill-down options, whereas marketing colleagues often have more interest in central KPIs. A dashboard for the management board usually needs a lower level of detail than a dashboard for special departments.

It’s better to create different versions of a dashboard instead of trying to make everyone happy with one view. In modern dashboard tools you can quickly and easily adapt existing visualizations and then offer different versions separately.

2. Create stories with your data

Data and results have a special impact when told as a story. Focus on the questions your target audience will have and visualize the data in a logical and thrilling order. A dashboard needs a leitmotif. The order of charts should be based on the interest of the target group.

How should the user proceed from result A to result B? What data must be shown first to set the context for the following data? Storytelling within reports and dashboards is a very powerful way to get your target audience attracted. Further useful may be e.g. appropriate headings, interpretations and explanations. Pictures can help to clarify your story.

3. Focus, focus and focus

A very common mistake derives from the idea to provide as much data and results as possible. Overloaded dashboards with unattractive information for the target person, have no right to exist. The added value of a good dashboard lies precisely in bringing important information to the point. Simplicity and clarity are king. And if the user wants more information, you may provide him with some drill-down options.

But usually, it’s much more difficult to get things straight to the point than to get lost in details. Unfortunately, this applies to dashboards as well as to all other forms of data visualization.

4. Not only bar plots: choose an appealing design

Example: Aster diagram. This chart type is suitable for a comparison of different brands. In the center a benchmark value can be displayed.

Undoubtedly one of the most important success factors of good dashboards is a clear and appealing design. First of all, it’s about choosing the right visualization: bar charts can be very useful, but there are many other types of graphs to present data. Depending on the topic and objective of the dashboard, it could also make sense to use pictures or text elements. In addition, the corporate identity should be clearly visible.

Don’t worry: you don’t have to reinvent the wheel, there are many templates and examples of good dashboards out there.
Even with dashboards, orient to visual standards that users are already familiar with. Use known icons and navigation elements. A good UX design is key for making the dashboard an important tool in the company. Therefore, test the dashboard to some users before going live. But don’t worry: you don’t need a complex usability test scenario. But go out and watch your target audience during use and take the feedback to improve the dashboard.

5. Let the user play

A major benefit of online dashboards is that they are interactive, not static as PowerPoint reports or Excel spreadsheets. Provide users with the opportunity to delve deeper into data by offering filters or different target groups to choose from. So users can customize the dashboard for their purposes and “play” with data. This interactivity increases the added value of a dashboard and ensures greater use.

Keep in mind, however, that the more possibilities of analysis and customization you provide, the more you have to train users beforehand. Otherwise there is a risk of mis-interpretation. Finding the right balance between too much and too little data in a dashboard is an art.

6. Choose the right dashboard tool

Using a good dashboard software the key factors mentioned above should be implemented easily. But there are also some technical requirements to consider. Of course, the dashboard should also work on a smartphone or tablet device. And ideally in all common browser versions. Since data volumes are getting bigger and the time of your target group ever shorter, loading times must also be as short as possible. Flexibility in data sources is another feature that can decide between success and failure.

It is also good if a dashboard offers export interfaces to Powerpoint and Excel, so that results can be quickly compiled for Executive Board / offline reports as needed. And last but not least: most data is sensitive. Data security should be guaranteed and data protection rules have to apply.

DataLion at the Digital Challenge 2018

In mid-June, numerous specialists and interested parties from agencies, institutes and companies got together in Munich in order to discuss the latest developments in digitization.

We were very much excited to be there as well: our CEO and founder Dr. Benedikt Köhler introduced the new world of data science. In a live example he demonstrated how one can use Foursquare to avoid being marked as a tourist when visiting an unknown new city.

The speeches and presentations where up-to-date and rather widespread thematically. The participants were presented with examples of the applications of AI and Blockchain, as well as Best and Worst Cases of Influencer Marketing.

Johannes Ceh´s keynote topped off the conference by highlighting the opportunities and risks of digitization. The networking afterwards lived up to the expectations and the speeches were discussed thoroughly at the After Show Party.

The Five Most Creative Music Visualizations

“Data is power”: by now an established fact. “Music is power”: a universal truth. So what do we get, when we creatively combine the plethora of available data on music with analyzing techniques and powerful software? We gain knowledge, insight and tremendous inspiration. We have gathered some really interesting and inspiring interactive and non-interactive visualizations on the evolution of music as well as on current distinctive trends. Enjoy!

Using data from the Billboard Top 100 Data 1958 – 2016, The Pudding´s Matt Daniels  has visualized the evolution of music taste on a month-to-month basis over the years: every top 5 song from 1958 to 2016 in the U.S.. Headphones required – it´s a “soundalized” visualization!

Kaylin Pavlik, on the on the other hand, in her Blog post „50 Years of Pop Music” has used R and data from the Billboard Year-End Hot 100 to offer a more quantitative insight into the evolution of Pop from 1965 to 2015 in the U.S..

Colin Morris (again of The Pudding) is putting one hypothesis into question: Are Pop Lyrics Getting More Repetitive? . The author used the Lempel-Ziv algorithm to measure repetitive lyrics with compression. The higher the compressibility of a song, the more repetitive its lyrics are. So seems like Rihanna´s Lyrics aren’t as much of a poetry as Frank Sinatra´s used to be! Wait, we did see that coming, didn´t we?

On a more international level, Spotify and open source platform CARTO have created the “Musical Map of the World”. The interactive map is making use of Spotify´s data from cities all over the world to give them their special “musical character”. You want to know how Germany sounds like? Click on the country to listen to its distinctive music!

Brady Fowler of Decibels and Decimals is not a friend of classifying music through genres. So he used Spotify data and Python iGraph to visualize the connection between artists and their music. The beautiful graph is the outcome of clustering the artists into groups, based on the listening habits of Spotify users.

Did you find the visualizations as interesting as we did? What would you add on the list? We are looking forward to your input.
