Visualization with MATLAB  By Peter Webb, MathWorks  Many
organizations make their data publicly available on Internet
servers and provide an interface for extracting slices or
sections of that data.  Analyzing this kind of data with MATLAB
was once a complex process-first retrieve the data somehow, then
get it into MATLAB for analysis. Today, using the MATLAB
interface to Java, you can write MATLAB programs that
incorporate both the data retrieval and analysis steps in a
single M-file; Java has classes and functions that make it easy
to capture data from Internet sources.  MATLAB programs for
Internet data retrieval and analysis have a three-part pattern:
• Open a specially formatted URL, creating a stream of data.   •
Read the data stream into MATLAB variables.   • Analyze or
visualize the data.  This pattern can be applied to data of any
type. For simplicity, the example code presented below uses
