{"version":"1.0","type":"rich","title":"question1","description":"This example shows the distribution of sepal lengths across iris species using a pie chart, with each species (setosa, versicolor, virginica) colored distinctly and accompanied by a legend and percentage tooltips. It loads the Iris dataset from a GitHub gist via `d3.csv`, parses numeric fields, and uses `d3.pie` and `d3.arc` to generate the chart. The visualization is rendered as an SVG, with colors assigned by species and a title displayed above the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/92d45dcb524d439680928b6328f55411?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
