{"version":"1.0","type":"rich","title":"A2 Ques 1","description":"This example presents a donut-style pie chart that visualizes the distribution of smartphone types from a CSV dataset, labeling each slice with its category and count. The chart uses D3 v5’s `d3.pie` generator and `d3.arc` to compute and draw the arcs, with a categorical color scale from `d3.scaleOrdinal` and `d3.schemeCategory10` to differentiate slices. A legend is added to the right, and the data is loaded via `d3.csv` from a GitHub gist.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b374d5c020254470810c44cf1df6d641?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
