Wolfram launches computational document format
Wolfram, the maker of Mathematica and Wolfram Alpha, has recently launched the computational document format (CDF) — a document format that allows authors to embed interactive diagrams, charts, and graphics in documents. The readers of CDF documents are allowed to change and adjust variables for exploration purposes.
The short video below introduces CDF.
Mathematica is required to create CDF documents, while the free CDF reader is needed to view them.
