{"version":"1.0","type":"rich","title":"Pie chart-rohitha","description":"This area chart visualizes the total purchase amount in US dollars by customer age, using shopping trends data loaded from a CSV file via `d3.csv`. The chart applies `d3.rollup` to aggregate and sum purchases per age, then renders the result as an SVG path generated with `d3.area`. Axes are drawn using `d3.axisBottom` and `d3.axisLeft`, with linear scales (`d3.scaleLinear`) mapping age and purchase totals. A blue filled area with a darker stroke highlights the distribution, while axis labels clarify the variables.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c0404a0cfbc54665bc2a68756a03f53e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
