{"version":"1.0","type":"rich","title":"Activity 7","description":"This example shows the market share of smartphone brands as a static pie chart with a legend identifying each brand by color. The visualization is rendered as an SVG using D3.js v5, with data loaded from a CSV file hosted on GitHub. The code uses `d3.csv` to parse the data, `d3.pie` to compute the angular layout, `d3.arc` to generate the pie slice paths, and `d3.scaleOrdinal` to assign colors from a predefined categorical palette. The chart includes a legend of circles and text labels, along with a title and axis labels for context.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e478472af51e413ead70c7e671c9d5e3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
