A yellow, smiling face with red eyelashes (rendered as arcs) is drawn as an SVG. The eyes are black circles with red lash arcs above them, built using `d3.arc`. The lashes animate vertically via chained `transition().duration()` calls, moving up and down. The face is centered using a `g` element transform, with the data visualization code in React, using d3.v5 to select the SVG and append shapes.
