I am currently doing some simple svg files by hand. They contain simple graphics. Think of a circle representing a planet and a smaller circle passing in front of it representing a moon. I use the animate command to successfully do that.
I am looking for a graphics editor which will aid me. Inskscape does not support animate. BoxySVG does not support animate either. I would hate to step up to a tool for more complicated vector graphics only to have to come back and add code by hand at the end.
Can someone recommend a solid, robust, open-source svg editor program that is is aware of animate out-of-the box?
Edit
Thanks for the answers thus far. What I'm actually looking for is a program which will let me create some free-standing .svg files which I can give or distribute. Must be .svg format files, can be viewed with or without a web browser. The text-based vector format is important to me, because I may programmatically alter some attributes of the image, like size, color, speed of transit, etc.
