{"version":"1.0","type":"rich","title":"Reusable Barley PunchCard Chart v5 - static","description":"This punch card chart visualizes barley yield data from 1927-1929 across multiple sites and barley genotypes. The chart uses a static SVG rendering with a reusable D3.js v5 module pattern, featuring circular marks whose radius encodes yield magnitude and color distinguishes barley genotypes. The visualization incorporates D3's `scalePoint` for the categorical y-axis, `scaleLinear` for the year-based x-axis, and `scaleSqrt` for radius scaling, alongside ordinal color mapping. The data is sourced from a CSV file containing yield measurements for different barley varieties across experimental stations in Minnesota.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0acdc29f06a04921b134d118c72bf3e1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
