make a face with D3.js
A blue circle forms the head of a face rendered in SVG, with two dark eyes, rectangular eyebrows, and an arc-based mouth created using D3's `arc` generator. The eyebrows animate vertically via chained `transition().duration()` calls on a grouped `<g>` element. The visualization uses D3 v5 within a React framework, selecting the SVG and appending shapes with `select` and `append`, all centered by translating the group to the viewport midpoint.
