Hi, I made this map/visual diagram of the web's APIs. One of the interesting things you can see is the emerging technologies, like CSS Houdini (https://developer.mozilla.org/en-US/docs/Web/Houdini). Another is alternative and less popular technologies, like XSLT for styling (https://developer.mozilla.org/en-US/docs/Web/XSLT) or SVG as a markup language. (https://www.w3.org/TR/SVG11/)

It helps people understand the capabilities of a modern web browser easier.

The color-coding is intended to help web developers think on if they can use as a feature on their site. If your audience is on a modern web browser (not IE 11), the medium shade of green is enough. If you only need some users to have the feature, then dark green is enough. If you only care about Chrome, you can use the APIs in blue.
