{"version":"1.0","type":"rich","title":"Assignment7 Pie Chart ","description":"This pie chart displays the distribution of energy use across five sources—Petroleum, Natural Gas, Renewables, Coal, and Nuclear—using data from the energy_use.csv file. The visualization loads data with `d3.csv`, calculates the arc paths using `d3.pie` and `d3.arc`, and renders each slice as a `path` element in SVG with an ordinal color scale. A legend on the right side, built with `selectAll` and `append`, maps each colored rectangle to its corresponding energy source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f92dfe3ac0444e392cb412ddb6dd91b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
