Hi, My name is Lars Lindqvist and I wonder if there are any packages which makes it possible to include diagrams in documents on the WWW in a conveniant manner? What I have in mind are packages similar to the existing packages for the creation of diagrams in e.g. LaTex. Very simple diagrams can probably be specified using the table construct in MathML but problems occur quite rapidly as the diagrams become more complicated. MathML is simply not intended for specification of such diagrams. See e.g. the last paragraph in section 7.1.5.2 of the MathML specification http://www.w3.org/TR/1999/WD-MathML2-19991222: " Finally, apart from the introduction of new glyphs, many of the situations where one might be inclined to use an image amount to some sort of labeled diagram. For example, knot diagrams, Venn diagrams, Dynkin diagrams, Feynman diagrams and complicated commutative diagrams all fall into this category. As such, their content would be better encoded via some combination of structured graphics and MathML markup. Because of the generality of the `labeled diagram' construction, the definition of a markup language to encode such constructions extends beyond the scope of the W3C Math activity. (See http://www.w3.org/Graphics for further W3C activity in this area.) " Following this suggestion I have made some initial attemts to construct an XML markup language for diagrams. I have also written a XSL (Extensible Stylesheet Language) schema that transforms diagrams specified in this language to a VML (Vector Markup Language) specification which can be rendered by e.g. Internet Explorer 5. There is a lot of work involved in a project like this so I am really interested to hear about other attempts and experiences before I continue. /Lars Lindqvist ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
