{"version":"1.0","type":"rich","title":"Moon Calendar 2020","description":"The Moon Calendar 2020 displays the moon’s phase for every day of the year in a grid, with months on the y-axis and days on the x-axis. Each moon is rendered as an orthographic projection of a circle using `d3.geoPath` and `d3.geoOrthographic`, with phase computed from a simple lunar-cycle formula. Clicking anywhere highlights the current day’s moon with a fading red ring, animated via `transition`. The visualization uses `d3.scaleLinear` for days, `d3.scalePoint` for months, and `d3.timeDays` to generate the date sequence.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8cf0ddea0db64f9f9c51b3191ab8311b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
