{"version":"1.0","type":"rich","title":"Task-9-Q1","description":"This example shows a pie chart of sales totals grouped by product line, with a tooltip that displays the product name and sales value on hover. It loads a CSV file from a GitHub gist using d3.csv, then aggregates the data with d3.rollups and d3.sum. The chart is rendered as SVG using d3.pie and d3.arc, with a color scale from d3.schemeCategory10. A legend and axis labels are added manually, and a hover tooltip is implemented with D3 mouse events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c4fd4c85dcfa408d914f3b09de0dba2d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
