{"version":"1.0","type":"rich","title":"activity_task2","description":"This example displays a stacked bar chart comparing the values of Nitrogen, normal, and stress conditions across four groups: banana, poacee, sorgho, and triticum. The visualization uses d3.stack() to aggregate the CSV data into stacked segments, with d3.scaleBand() for the categorical x-axis and d3.scaleLinear() for the y-axis. A separate SVG legend is created using d3.scaleOrdinal() to map each subgroup to a distinct color. The bars are rendered as SVG rectangles, with axes labeled \"Group\" and \"Value\".","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d6f1632f5cfb4acf85697583aa92f4bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
