Airport Clocks displays a grid of analog clocks, each labeled with a city name, all ticking in real time. The animation is driven by `d3.local()` for timezone-aware time, while each clock face is drawn using `d3.component` to create a reusable SVG component with configurable properties. The code renders clock numbers, tick marks, and rotating hands via SVG transformations, with a central `axle` group per clock. A grayscale color interpolation (`d3.interpolateLab`) tints the faces, and daylight savings adjustments are applied manually. The clocks are laid out with inline-block styling, creating a world-time dashboard.
