{"version":"1.0","type":"rich","title":"task9","description":"This example visualizes the distribution of flower species in the Iris dataset as a pie chart, with a color-coded legend displayed beside the chart. It uses D3 v7 to load CSV data via `d3.csv`, aggregate counts with `d3.rollups`, and render SVG arc paths generated by `d3.pie` and `d3.arc`. Colors are assigned through `d3.scaleOrdinal` with `d3.schemeCategory10`, and the legend is built dynamically in HTML with styled divs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/aa86c3ce54894b37b90bf77969d49500?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
