{"version":"1.0","type":"rich","title":"Activity7 Q1","description":"This pie chart visualizes the distribution of population (in millions) across income brackets, using a dataset loaded from a GitHub gist. The chart is rendered as an SVG with slices colored by income bracket categories, and includes a legend and axis labels for context. The visualization is built with D3 version 7, employing the `d3.pie` layout, `d3.arc` for generating slice paths, and `d3.scaleOrdinal` with `d3.schemeCategory10` for color mapping. Data is parsed from CSV format and numeric values are coerced to numbers for aggregation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9044a97771d44ff1a2cf9e13c729d7f1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
