There are several ways in which we can deploy our visualizations and share them with people. We can save our Mathematica notebooks in the CDF format. Mathematica provides a free CDF player that can be downloaded to view Mathematica code and visualizations interactively. To deploy the system in your websites, you can subscribe to the webMathematica interface. Starting from Version 10, Mathematica will have an online interface that you can buy. The Wolfram Demonstrations site also provides a way to host our notebooks online. Details of preparing a notebook to upload in this site can be found in the documentation.
