{"version":"1.0","type":"rich","title":"Questuion 2 ","description":"This example displays a stacked area chart comparing three categories (A, B, C) over a five-year span from 2010 to 2014. The visualization uses D3.js v7, specifically the `d3.stack`, `d3.area`, `d3.scaleBand`, and `d3.scaleLinear` functions to compute the stacking and generate the SVG paths. Each category is colored using the categorical palette `d3.schemeCategory10`. The chart includes labeled axes for year and value, with margins applied to the SVG canvas for proper layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a2c5346e7a6546ba83295990b5c70a1e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
