For the moment, there is nothing here. I do have plans to create an SVG playground here though. An easy to use environment (like ShaderToy) that lets you create SVG effects and animations using little code. You could then generate the actual SVG that contains as little content as possile. You could also generate glue code to use the SVG in React/Vue/Svelte/etc. Even video creation from your animations should be possible. And most importantly, you should be able to easily reuse what effects others have made, similar to how you reuse components in front-end frameworks.
Until then, you can find me here.
