{"version":"1.0","type":"rich","title":"task2","description":"This example presents a stacked bar chart that visualizes the distribution of three product categories (Product A, Product B, and Product C) across four geographic regions: North, South, East, and West. The chart uses SVG rendering to display the bars, with each product assigned a distinct color from the `d3.scaleOrdinal` and `d3.schemeCategory10` color scale. The code utilizes `d3.stack()` with `d3.stackOrderNone` and `d3.stackOffsetNone` to compute the stacked segments from the hardcoded data. A legend is appended to identify each product category, and the chart dimensions are fixed at 600 by 400 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/52c5d3d180b04a27bb1f7d161a675952?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
