"There are many data visualization tools available and I've used quite a few of them. They include Google Charts, Tableau, Grafana, Chartist.js, FusionCharts, Datawrapper, Infogram, ChartBlocks, and D3.js. My favorite is Google Charts. This is because it is easy to use, robust, widely accepted and the licensing fees are low. Another reason I prefer Google Charts is that it can be customized to make it better suited to the specific project I'm working on. Since most of the work I do is similar, once I have tailored the tool to my needs I don't have to reconfigure it each time I use it."

This question is similar to the one about statistical software programs in that it is attempting to discover your technical knowledge and your familiarity with the tools the company you are interviewing with uses. Again, the best response is a direct one, stating your knowledge of software tools, your preference, and the reason for your opinions.

I prefer Tableau because it offers a variety of visualization styles, is easy to use, and can handle large data sets. I also like Tableau because their help desk is very responsive and open to suggestions from the user community. It isn't a true open-source software, but the product is continuously being improved by the developers and the company's customers."
