Tableau Public is a free data visualization tool aimed at online publishers and academics. It can be used to create an interactive visualization, and also enables users to publish it to the web as an embed or share it via a link. Users must download the desktop interface, and all projects created through the system are saved remotely to the Tableau Public server rather than to the user's local machine. It is availabe for both Windows and OS X, and has a visual interface with a simple drag and drop process.
