{"version":"1.0","type":"rich","title":"Fork of Moon Calendar 2022","description":"This visualization displays the moon’s phase for every day of the year 2022 in a calendar grid, with months on the y-axis and days on the x-axis. Each moon glyph is drawn using `d3.geoOrthographic` and `d3.geoPath` to project a circle based on the phase angle, calculated from a simple lunar period formula. The SVG renders a dark circle with a light path overlay to represent the illuminated portion. Clicking the graphic triggers an animated red ring that expands and fades to highlight the current day.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/25c8f077ade6424e8b174b4375237048?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
