SVG: Draw rectangles and triangles. If you don't have a script tag in it, totally declarative.

You don't draw line by line. You describe what you want and have the engine work it out. Just because that description can be complex such as a <path> definition doesn't detract from this point.

Kinda like SQL. Describe the set of data you want from other sets of data and have the engine work it out. It's set theory. In math, sets can have conditions, can be combined, can be filtered, and all without a single function or loop in sight. Ergo declarative, not functional or imperative.

SQL is a DSL for set theory with some extensions tacked on. You can use functions with SQL, but its core is perfectly adequate without them.
