This visualization displays eight analog clocks for cities such as San Francisco, New York, London, and Sydney, each showing the current time with hour, minute, second, and millisecond hands. The clocks use React components with D3.js for SVG rendering and animation, leveraging d3.timer for smooth hand movement and d3.utcDay for calculating time zone offsets. Styling is configurable through a centralized configuration file, and the layout presents all clocks in a responsive, wrap-around grid.
