How to make dotml

How to render dotml in a chart? According to the website here :

Getting graphs from your data is a three-step process. First create or manually enter a file> XHTML (or any other XML) containing DotML elements.

Use http://www.martin-loetzsch.de/DOTML "as the namespace identifier for DotML elements.> If you want to test your DotML elements, use the DotML scheme.

Second, apply the script "generate-svg-graphics.bash" in the input file. It applies a stylesheet> dotml2dot.xsl and generates an SVG diagram and a CSS file containing the size> SVG diagram for each element of the DotML graph. Please see "generate-svg-> graphics.bash" for the necessary environment variables and parameters.

Third, if a DotML graph is embedded in an XHTML document, the XSLT stylesheet "embed-> svg-graphics.xsl" replaces the DotML graphic elements with the inclusion of generated> SVGs. See "Embed-svg-graphics.xsl" for details.

I have already entered the XML code, but I don’t know what the rest of the steps mean. If anyone could explain how to do this at a very simple level that would be fantastic.
