{"version":"1.0","type":"rich","title":"Stack Trial","description":"This visualization displays a stacked area chart showing how three groups contribute to a total value over time, with each group’s portion layered on top of the previous one. The data, loaded from a CSV file, is processed using `d3.nest()` to group entries by year, then `d3.stack()` to compute the stacked series. The chart uses `d3.scaleLinear` for both axes, an ordinal color scale for group differentiation, and `d3.area()` paths to render the filled regions. The visualization is built with D3 v4 and rendered as SVG within a React framework.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f0c395e199dd40ffa34646ad89ead841?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
