How interactive graphs are generated in Tableau

Question

I'm using Tableau software to create nice graphs for data visualization. Can someone tell me how such nice interactive graphs are generated? Do they support HTML5? Is there any nice graphical library available for this?

Answer 1

Lot of back end code is shared between tableau desktop & server just to generate images. The Desktop draw images on the screen while the Tableau Server draws into off-screen image buffers and then it sends the data as a series of JPEG tiles to the browser.

These shared code is customized in C++ by the developers from the Tableau Software.
For free visualization you can check out the free gallery from tableau public.
