What is used to write animation on the web (see example)?

Question

Animation

Since I'm not an expert on the web, I can't even imagine what things like this are made of:

Sometimes there are fully interactive sites like this example, sometimes the site is partially interactive: you press a button, some figure flies to a given point, etc. All this is of interest in order to create training schemes, all sorts of visual goodies inside the page. It is especially interesting if this can be built into a CMS (for example, Joomla).

If I am not mistaken, Lebedev had a link to this site.
It's done on canvas, svg is sometimes animated, and css3 has come a long way.
That is, in short, you can animate:
1. On pure html / css (google css3 animation)
2. On html / css / js - there are a huge number of examples, as an option, google jquery animate
3. svg animation
4. On canvas - what to google and so clear
