{"version":"1.0","type":"rich","title":"Activity 7 Question 1","description":"This example visualizes the distribution of grocery item prices by category as a pie chart, with a text legend displaying each category’s total dollar value. It loads a CSV dataset from a GitHub gist, aggregates prices per category using `d3.rollup` and `d3.sum`, and renders the chart with `d3.pie`, `d3.arc`, and an ordinal color scale (`d3.scaleOrdinal`). The SVG is drawn via D3 v6, and the legend is built as styled HTML divs, with data fetched asynchronously through `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/458a1a5378e0453886202d0a8131ce53?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
