A grid of small moon icons displays the lunar phase for every day of 2022, with months arranged along the y-axis and days along the x-axis. Each icon uses an orthographic projection with `d3.geoPath` and `d3.geoCircle` to render the illuminated portion based on a “Simple” phase calculation. Clicking anywhere on the chart animates a red ring around the current day’s moon via an SVG transition. The visualization is built with D3 v5, uses SVG for rendering, and derives its phase values from a fixed reference new moon timestamp.
