Why Data Visualization and Dashboards Matter

Data Visualization| Visual Data Analysis| Data analysis | | Alivia Smith

Data scientists spend days and days (if not weeks and weeks) cleaning and preparing data, building and training models, and eventually trying to come up with interesting insights or delivering valuable data products to improve overall company performance. So why does data visualization matter?

The thing is, what data teams are actually doing remains very obscure for a lot of business-oriented people out there including decision makers. Not only is it frustrating on a personal level because data scientists feel undervalued, but it can also more importantly prevent the company from actually using and taking into account data-generated insights. Which is kind of annoying. And costly.

There are probably several reasons for this misunderstanding. But most of the time it has something to do with business people not figuring out how to picture the whole data science process. They carefully listen to data scientists’ final recommendations but actually end up leaving the room feeling in the dark. Why?

Because even though they trust their data scientists, it’s always frustrating to accept advice without having full understanding and visibility into the secret sauce behind it all.

Basically, all the complex technologies and programming languages involved in the data science process make it hard for non-technical people to understand it. That’s when data visualization comes into play and allows less technical profiles to penetrate the black box and to really understand what’s being produced in the company’s data department.

What You Need To Know About Dashboards

So you get it: data visualization is super-duper important. It’s basically the key deliverable allowing business people to understand data scientists’ work AND what their final recommendations are. In the end, it’s all about communication. But - believe it or not - there is something even greater than data visualization and it’s dash… wait for it… boards!

So what is a dashboard really? Dashboards are basically great places where you can pin whatever you want and organize the whole thing however you like (with sections, titles and so on). And by whatever you want what I really mean is maps, interactive graphs, forms, datasets previews, python notebooks, web apps, and so much more. How cool is that?

The only thing you need to make sure of is that the information you choose to display is actually going to be useful. Either to your data scientists if they need to use the dashboard as a notebook or to your readers, who might access the project dashboard and data-generated insights without necessarily having to dive into the depths of datasets, recipes, and so on.

Dashboards Are Not Data Visualization

The main difference between basic data visualization and dashboards revolves around how frequently data is updated. While data visualizations are just generated from data, dashboards are regularly updated according to dataset modifications. Plus, dashboards generally tend to work with various shapes and sizes of datasets, which is a real asset.

If you’re interested in knowing more about the difference between dashboards and data visualization, you might like this article - and more generally this website - I came across during my investigation.

Dashboards not only allow business-oriented users to understand what is actually behind that huge amount of data by displaying graphs, tables and so on, but they also enable them to play with data and to easily extract what they need from it.

Simple use case: just by filling in a basic form from the dashboard with a customer id, marketing people can for instance be enabled to see whether or not this precise customer is likely to be a potential churner.

So to wrap it all up, dashboards are an important step in a data science project that makes data accessible to the company’s business-oriented people.

Last but not least, dashboarding is a great way for technical people to work more efficiently together as a team. As they work on different parts of a project, data scientists can gather their insights on the project dashboard to share their results with their colleagues. That’s part of why we claim Dataiku is a collaborative tool. Want to give it a go?
