{"version":"1.0","type":"rich","title":"Activity 7_ Question1 ","description":"This visualization shows the 2023 U.S. utility-scale electricity generation mix as a pie chart, with each slice representing an energy source’s share of total generation. D3 v7’s `d3.pie` and `d3.arc` generate the slices, while `d3.scaleOrdinal` assigns colors from the Tableau10 scheme. Percentage labels appear on slices exceeding three percent. A scrollable legend, sorted alphabetically, lists each category with its exact share. Data is loaded from a CSV via `d3.csv`, and the chart is rendered as SVG with a responsive `viewBox`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f806668a27fe4d5eba7918502229a197?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
