{"version":"1.0","type":"rich","title":"Activity7_task1","description":"This visualization displays a pie chart of the top 15 countries by happiness score, using data loaded from a local CSV file. Each slice represents a country’s overall happiness score, with the chart using d3.pie() and d3.arc() to compute and render the arcs in SVG. A color scale from d3.scaleOrdinal with the Tableau10 scheme fills each slice, and white text labels show country names at each arc’s centroid. A legend, also generated with D3, maps each country to its corresponding color.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e167d3d10b7440cfa126ca2ffa5d20c0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
