Visual Editor for SVG? (Scalable Vector Graphics)

It would be interesting to know whether any companies or researchers, are working on a visual development environment for creating SVG (Scalable Vector Graphics) movies, and interactive components. This would be very useful, Flash, Viewlet Builder, and many other tools are good for creating movies and interactive presentations. However there is a need for something that has this ease of use, and produces the same kind of output, using open standard SVG.

This would provide the capability to represent each picture in an alternative way for the blind. Without this functionality, web developers need to manually provide a separate representation for blind people. I doubt that every web developer does this. The SVG output could be the basis of providing a Flash movie, from which information could be extracted automatically. This extracted information would provide the alternative representation for blind people and non-Flash users. Also such a tool would be very good for allowing information to be extracted from the picture, e.g. values and labels from a graph, or attributes from a part diagram.

If the SVG items are grouped in an appropriate way this could make it possible to allow extraction of objects and properties represented in SVG that have a clear meaning. Adobe has acquired http://www.adobe.com/aboutadobe/invrelations/adobeandmacromedia.html, so perhaps they're doing something similar to Flash but with an SVG output? It would be good to see an automatic way of providing the sort of functionality illustrated at http://www.cems.uwe.ac.uk/~phale/InteractiveSVGExamples.htm. This is output automatically from a taxonomy represented in Protege, through a Decision support system DecisionPro http://www.vanguardsw.com/.

This sort of thinking ahead by software suppliers would make it much easier for ordinary users to provide good interactive content for the web. This is the basis of 'End User Development', a technique for making it easier for computer literate non-developers to create software. In this case the application of this technique would be enabling the construction of accessible interactive web pages.

Editor for static SVGs:
- http://www.inkscape.org/ (what I use)
- Adobe Illustrator
- Sketsa

Just did a search for editors for animated SVGs, I've never used any of these products:

Thank You, I'll look at these.

"WebOS" from www.morfik.com is an interesting Ajax development tool - but still at the "beta" stage.
If you can figure out how to display a simple interactive SVG diagram using "WebOS" - please let me know!
I think you'll agree - the potential is mind blowing.

Thank You John

I'm having a look at Mortfik now and definitely will try and create an interactive SVG diagram as soon as I have time. There seem to be some pretty good Rich Internet Application development environments, all coming at once, and I'm linking my web pages to each. I've done so, for all the tools mentioned in these comments, and created a simple application with Adobe Flex 2, but this isn't SVG based, it just displays editable text. I also want to try out Tersus Open Source Visual Programming Platform.

It's hard to keep up with the rate these tools are being released, but that's a nice problem to have. I'll adapt the interactive SVG examples, using one or more of these application developers, as soon as I have time.

If anyone creates such examples before I get around to doing so, please let me know and I'll link my pages to this.

I like to see a good illustration in the websides, even if the text isn´t good, i think the graphics have too much importance.I must to say this blog contain a great graphics and that´s what i´ve been looking for.Actually
costa rica investment opportunities
introduce wonderful graphics about different things.
