{"version":"1.0","type":"rich","title":"Pie Chart","description":"This pie chart displays monthly expense categories—Rent, Food, Travel, Shopping, and Bills—with proportional slices and a labeled legend. Built with D3 v7, it loads data from a CSV file, computes arc paths using `d3.pie()` and `d3.arc()`, and positions category labels via `labelArc.centroid(d)`. A categorical color scale (`d3.scaleOrdinal`) assigns colors, while the SVG rendering includes a title and a legend showing each category’s value. The chart is generated entirely with SVG elements and a custom legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f68df4cc53cb43c6934baea36acfec0c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
