Tableau Software
Tableau Software is perhaps the best known platform for data visualization across a wide array of users. Some Coursera courses dedicated to data visualization use Tableau as the underlying platform. The Seattle-based company describes its mission this way: "We help people see and understand their data."
This company, founded in 2003, offers a family of interactive data visualization products focused on business intelligence. The software is offered in desktop, server, and cloud versions. There's also a free public version used by bloggers, journalists, quantified-self hobbyists, sports fans, political junkies, and others.
Tableau was one of three companies featured in the Leaders square of the 2016 Gartner Magic Quadrant for Business Intelligence and Analytics Platforms.
