{"version":"1.0","type":"rich","title":"Fork of Hello VizHub","description":"This D3.js pie chart visualizes the global smartphone market share from a CSV file, displaying each brand or model as a colored slice with a percentage label and a legend on the right. The chart loads data from a GitHub-hosted CSV, dynamically detects label and value columns, and optionally normalizes values to percentages. It uses `d3.csv`, `d3.pie`, `d3.arc`, `d3.scaleOrdinal` with the Tableau10 color scheme, and renders the visualization as an SVG. The code also demonstrates flexible CSV header detection and data preprocessing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cfb65fd1ed764f0cab6ba1d3d2824b58?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
