{"version":"1.0","type":"rich","title":"Rahul area chart","description":"This area chart depicts the average petal length for different flower species from a CSV file. The visualization uses a smooth, monotone curve to connect the average values, with the area beneath the line filled in a semi-transparent steel blue. The chart is rendered as an SVG using D3.js v7. The code calculates the per-species averages via `d3.rollup` and `d3.mean`, then maps the categorical species data to a band scale and the numeric averages to a linear scale. The area is generated using the `d3.area` API, while axes are added with `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4db7f51e48dc4fe0946f0a1f2bfc6af4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
