If you want to bring your websites or blogs to live you should take a look at BonsaiJS. It is a lightweight library with an intuitive graphics API and an SVG renderer. It makes creating SVG based web assets and animations easy.
To see and understand the power of BonsaiJS, I suggest trying out their Orbit online editor. It is playground to test out BonsaiJS code. It will demonstrate how SVG graphics can be achieved with a few lines of readable code. More importantly, I recommend trying out sample codes and what they produce.
I hope you will BonsaiJS useful and integrate it into your current and future webs development projects. Even if you don't plan to develop websites and stand-alone blog, I think you can make use of Orbit online editor to create graphics and animations for other purposes.
