{"version":"1.0","type":"rich","title":"Fork of Moon Calendar 2021","description":"This visualization displays the moon’s phase for each day of 2021, arranged as a calendar grid with months on the vertical axis and days on the horizontal axis. Each moon is rendered via `d3.geoPath` and `d3.geoOrthographic` with circles and paths showing the illuminated portion based on a simplified lunar phase calculation from ben-daglish.net. Clicking anywhere on the SVG animates a red ring to highlight the current day using a `transition` with duration and stroke attributes, while axes are built with `d3.axisTop` and `d3.axisBottom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/35d96b90b6ea4a5389db54f72f833256?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
