Let's construct a beautiful flower using a clever arrangement of simple shapes.

A Petal

Let's first compose a petal using rectangle, circular_sector, rotate, beside, and above.

Outlined Petal

Let's overlay a petal and a slightly smaller petal to build a petal with an outline.

A Ring of Petals

Now let's build a ring of 6 petals.

A Flower

Finally, let's compose several rings, each one a bit smaller than the previous one. Let's also change the lightness of the fill color of each ring, such that the innermost ring of petals is the lightest.
