I am not using SVG right now but I have used it on two different jobs about a year ago. In both cases, I was doing numerical data processing and needed to graph or plot some of the results. In ine case, I had my data in xml files or could easily get it into xml files, and I used xslt to produce the SVG graphs. In the other case, I was producing the data using Python, and I used Python to write the SVG. In both jobs, once I got things working, I produced a lot of SVG using batch-like processes. In some cases, I also captured typeical screen shots and pasted them into Powerpoint presentations - don't laugh, it was by far the easiest way. It was a bit hard to climb the learning curve to the point that I could get all the different pieces of the graphs coordinated and placed correctly relative to each other. Fortunately, I had quite a lot of Postscript experience from years ago - I probably would have used Postscript if SVG was not around. I was very happy I could use SVG and liked it much better than working with Postscript - although PS can do a lot more or at least it is easier to figure out how (bear in mind that I did a lot of FORTH programming in my earlier days). But SVG is missing one capability that really gets in the way of using it in complex applications, so far as I am concerned. That is the lack of font metrics. You cannot find out how big any piece of text is, so you cannot programatically line many things up, you cannot properly break lines, etc. I hope that the SVG language experts have or will figure out a way to deal with that, because I think it is essential. The other thing I noticed is that the anti-aliasing took away too much sharpness from the images, at least with the Adobe viewer. I would like to be able to adjust the balance of anti-aliasing and sharpness. Cheers, Tom P
