Tableau Software‘s shares soared 13 percent on Tuesday following the announcement that the data analytics provider has partnered with Narrative Science, a Chicago-based company that develops natural language generation (NLG) tools. The result of the partnership is Narratives for Tableau, a free Chrome extension that automatically creates written explanations for Tableau graphics.
Let’s say, for example, that you have a chart — made with Tableau — of sales and profits of your business for a certain amount of time. The extension, which works with Tableau Server 10.0 or the free Tableau Public service, will generate a narrative description of the data by writing sentences such as “Sales and profit ratio moved in opposite directions from January 2011 to December 2014,” as shown in this example.
“This extension was built from an extremely close collaboration between Tableau and Narrative Science,” Stuart Frankel, CEO of Narrative Science, wrote in an email to TechCrunch. “While sitting outside the platform, the UI and experience feel similar to the Tableau experience.”
